Biopsychology and neuropsychology

Intro

What is neuropsychology?

  • The neuropsychology studies the relationship between the brain and behavior through biological background.  
  • From neurosurgery, psychometrics, statistics and imaging of the functioning brain together, the need for the direction of neuropsychology arose.  
  • In neuropsychology there are two hypotheses: 1) the brain hypothesis and 2) the neuron hypothesis.  
  • The brain hypothesis holds that the brain is the source of behavior.  
  • The neuron hypothesis holds that the neuron is the building block of the brain.

What is biopsychology?

  • Biopsychology is the application of principles from biology to the study of human and animal behavior.
  • Biopsychology and neuropsychology are overlapping fields of study, the main difference being that in neuropsychology the focus is often on people with disorders of the nervous system, while in biopsychology the link between brain and behavior is examined in a broader way and animals such as rats and mice are also used in experiments to study behavior.

What is a neuron?

What is a neuron?

Neurons, also called nerve cells, are the fundamental building blocks of the nervous system. They act as messengers, transmitting electrical and chemical signals throughout the brain and body, coordinating everything from movement and sensation to thought and emotion. A neuron has a distinct structure:

  • Cell body (Soma): Contains the nucleus and is responsible for the neuron's overall function.
  • Dendrites: Branching extensions that receive signals from other neurons.
  • Axon: A long, slender fiber that transmits signals to other neurons or muscles.
  • Myelin sheath (optional): Insulates the axon in some neurons, allowing for faster signal transmission.
  • Synapses: Junction points between neurons where signals are transmitted via neurotransmitters.

What are the main features of a neuron?

  • Excitability: Neurons can be excited (more likely to fire) or inhibited (less likely to fire) by signals from other neurons.
  • Signal Transmission: Electrical impulses travel down the axon and trigger the release of neurotransmitters at synapses.
  • Neurotransmitters: Chemical messengers released by the axon that bind to receptors on dendrites of other neurons, influencing their activity.
  • Networks: Neurons connect to form complex networks, enabling the brain to process information and generate responses.
  • Plasticity: Neurons have some ability to change and adapt throughout life, influencing learning and memory.

Why is a neuron important?

Neurons are essential for all nervous system functions:

  • Communication: They transmit signals throughout the body, allowing organs and tissues to communicate and coordinate actions.
  • Sensory Perception: They enable us to perceive the world around us by processing information from our senses.
  • Movement Control: They control our voluntary and involuntary movements.
  • Thinking and Learning: They form the foundation for our thoughts, memories, and learning abilities.
  • Emotions: They play a role in generating and processing emotions.

How is a neuron applied in practice?

Understanding neurons has implications for various fields:

  • Neuroscience: Research on neurons helps us understand how the brain functions in health and disease.
  • Neurology: Studying malfunctions in neurons can aid in diagnosing neurological disorders like Alzheimer's or Parkinson's disease.
  • Psychiatry: Understanding how neurotransmitters influence mood can inform treatments for depression and anxiety.
  • Brain-Computer Interfaces: Future interfaces might interact with neurons to restore lost functions or control prosthetics.
  • Artificial Intelligence: Research on neural networks inspires the development of AI systems that can learn and adapt.

Practical example

Imagine you touch a hot stove. Sensory neurons in your finger detect the heat and transmit an electrical signal to your spinal cord. From there, the signal travels to your brain through other neurons. This triggers a response, making you pull your hand away to avoid further injury. The entire process relies on the coordinated activity of numerous neurons.

Critical comments

  • Oversimplification: The nervous system is incredibly complex, and our understanding of neuron function continues to evolve.
  • Limited Treatment Options: While we understand neurons, directly targeting them for treatment remains challenging for many neurological conditions.
  • Ethical Concerns: Advancements in understanding neurons raise ethical concerns regarding brain-computer interfaces and potential manipulation of behavior.

Live Lecture: Part 1 - Olfactory Social Neuroscience

Smell loss is inversely associated with color vision emergence, suggesting a trade-off between these sensory abilities. Humans, however, can outperform some animals in olfaction, but a certain level of olfactory strength is needed to be detected by humans.

The olfactory processing pathway involves the olfactory bulb, piriform cortex, and orbitofrontal cortex. The piriform cortex exhibits ensemble coding for odor identification, creating different maps of activity for various smells.

Smell serves functions such as judging edibility, avoiding environmental hazards, and social communication. Olfactory cues can convey identity, sickness, or diseases. Sickness affects attractiveness and liking, as observed in studies injecting individuals with saline or lipopolysaccharide (LPS).

The smell of fear is examined through individuals with a genetic variance related to body odor. The ABCC11 gene mutation results in almost odorless individuals. Fear-induced experiments show increased signs of fear

Knowledge Clips: Interacting with Others

The ultimatum game is an economic exchange between two people designed to measure fairness. While an economic perspective suggests human behavior is focused on personal gain, experiments, including the ultimatum game, reveal a more complex reality.

Prospect theory, based on experiments by Kahneman & Amos (1979), highlights the role of subjective experience in economic behavior. Loss aversion, where people have stronger emotional reactions to losing than gaining similar things, indicates a conservative and risk-averse nature. The ultimatum game involves a proposer and a responder, an extension of the dictator game with the option to reject.

Rejection in the ultimatum game is irrational and costly for both the proposer and responder. People consistently reject 30/70% offers and lower, showing aversion to inequity or unfairness. Two motivations for rejection include emotional commitment (anger/frustration/envy) and social preferences, aiming to restore equity and reciprocity through altruistic punishment.

The ability of smell in humans is actually very good, as demonstrated by research conducted by Porter et al (2007). In this study, people were required to follow a trail of chocolate oil using only their noses, with their eyes and ears covered. The research revealed that human beings are proficient at performing and following scent trails, guided by their sense of smell. Moreover, humans are capable of discriminating more than a trillion smells.

Why do we look down on our ability to smell?

→ We find it hard to talk about smells and name them. Odors operate below the surface, affecting lower brain regions shared with other mammals and reptiles (limbic brain regions and even lower, regions that produce survival instincts). This bias might explain why we perceive smells as less important to us.

What is a personality disorder?

A. An enduring pattern of inner experience and behavior that deviates markedly from the expectations of the individual's culture. This pattern is manifested in > 2 of the following areas:

- Cognition
- Affectivity
- Interpersonal functioning
- Impulse control

B. Inflexible and pervasive across a broad range of personal and social situations

C. Significant distress or impairment in social, occupational, or other important areas if functioning

D. Stable and long duration, and early onset (at least adolescence)

E. Not better explained by another mental disorder

F. Not attributable to a substance or another medical condition

The three P’s are important:

- Persistent
- Pervasive
- Pathological

→ Personality traits are diagnosed as a personality disorder only when they are inflexible, maladaptive, and persisting and cause significant functional impairment or subjective distress.

- Social interaction and affective bonding

Eye gaze varieties:

Eye gaze detection in babies:
- Newborns preferentially look at faces with direct gaze. They pay attention more to somebody who is looking directly at them.
- This is also associated with increased oxytocin levels in mothers (and fathers); this facilitates direct gaze → first development of social skills of babies

Testosterone: hypothalamus - pituitary - gonads (HPG) axis:
→ Testosterone drives dominance behavior in a highly dynamic manner.

Challenge hypothesis:
- High testosterone for competition and challenge
- Low testosterone for parental care and social bonding

Testosterone works recursively: it can build up, and it can decline.
→ It motivates us to go into competition with others, and by going into competition, the testosterone goes up too. So it motivates, but it also goes up by the motivation itself.
→ But if you lose these competitions, the testosterone will go down, and the motivation will decline as well.

Cortisol: hypothalamus - pituitary - adrenal glands (HPA) axis
→ Cortisol is produced in response to stress (reactive threat system: amygdala - hypothalamus - autonomous nervous system)

1. Cognitive Model: Bruce & Young (1986) vs. Neurobiological Model: Haxby et al. (2000)
   - Two models for recognizing faces, emphasizing cognitive and neurobiological aspects.

2. Occipital Face Area (OFA):
   - Early perceptual analysis of faces.
   - Strong fMRI activity in response to faces, sensitive to physical changes (e.g., haircut, skin color).

3. Fusiform Face Area (FFA):
   - Recognizing known faces.
   - Strong fMRI activity in response to faces, sensitive to identity changes.

4. OFA vs. FFA:
   - OFA primarily active in physical change conditions.
   - FFA primarily active in identity change conditions.

5. Superior Temporal Sulcus:
   - Responds to changeable aspects of faces and bodies (e.g., eye gaze, motion).
   - Stronger fMRI response to eye gaze relative to person identity.

6. Body Recognition:

NESBED Knowledge Clips Week 1: Part 2

Knowledge Clips Part 2: Amygdala and Emotional Processing

Amygdala Structure:
- Part of the limbic system
- Studied as a single structure in humans
- Evolutionary changes in amygdala size (BLA vs. CeA)

Low and High Routes (LeDoux):
- Visual processing routes in threat perception
- High route: Thalamus to visual cortex to amygdala
- Low route: Thalamus directly to amygdala for rapid fear response

Fearful White Eyes Experiment:
- Amygdala responds to fearful eyes unconsciously
- Urbach Wiethe disease impairs fear recognition
- Patient SM and South African patients show different responses due to specific amygdala damage

Amygdala and Threat Conditioning:
- Reactivity, attention, recognition, learning, memory, and regulation
- Amygdala's role beyond fear: emotionally intense stimuli, positive/negative experiences

Insula:
- Linked to disgust traditionally
- Also involved in taste, pain perception, and general bodily

Wat is de thalamus?

De thalamus is een grote, boonvormige structuur in de hersenen die zich bevindt net boven de hersenstam. Het fungeert als een relaisstation voor de meeste sensorische informatie die naar de hersenschors gaat, de buitenste laag van de hersenen die verantwoordelijk is voor hogere cognitieve functies z...

Wat is de hypothalamus?

De hypothalamus is een kleine maar belangrijke structuur in de hersenen die zich bevindt onder de thalamus. Het is een neuro-endocrien orgaan dat een centrale rol speelt in de regulatie van een breed scala aan vitale lichaamsfuncties, waaronder:

Over Biopsychologie en neuropsychologie

  • De biopsychologie onderzoekt hoe biologische processen, zoals hersenactiviteit en hormonen, ons gedrag en mentale processen beïnvloeden. De neuropsychologie is een specialisatie binnen de biopsychologie die zich specifiek richt op de relatie tussen hersenfuncties en gedrag, vaak door onderzoek naar patiënten met hersenbeschadiging.
