Bio: Localisation of Function

Question 1

<p>Cerebral Cortex</p>

Answer 1

<p>The thin outer layer of the brain's (approximately 2 mm) cerebral hemispheres that acts as the main information processing center. Sometimes called ‘gray matter’ it is the area densely packed with neurons.</p>

Question 2

<p>Nucleus Accumbens</p>

Answer 2

<p>The nucleus accumbens plays a key role in addiction, pleasure, reinforcement learning, aggression, and impulsivity. The nucleus accumbens has a significant number of dopamine receptors.</p>

Question 3

<p>Hippocampus</p>

Answer 3

<p>This part of the brain appears to play a key role in the consolidation of memory from short-term to long-term, as well as play a role in spatial navigation. There are several acetylcholine receptor sites in the hippocampus. Hippocampal cell loss plays a role in dementia, including
<br></br>Alzheimer's Disease.</p>

Question 4

<p>Physiology</p>

Answer 4

<p>The branch of biology dealing with the functions and activities of living organisms including the physical and chemical processes such as the nervous system and the endocrine systems.</p>

Question 5

<p>Reductionist</p>

Answer 5

<p>A common critique of the Biological Approach is that is it reductionist meaning it deals with the micro-level of research (the role of 1 gene or 1 neurotransmitter in the brain). Because it is so narrowly focused, the
<br></br>explanations can ignore other important factors in behavior.</p>

Question 6

<p>The Central Nervous System</p>

Answer 6

<p>Made up of the brain, spinal cord, and a complex networks of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body.</p>

Question 7

<p>Localisation of Function</p>

Answer 7

<p>The theory that specific behaviors may have their origin in specific parts of the brain.</p>

Question 8

<p>Limbic System</p>

Answer 8

<p>The middle part of the brain that is sometimes called “The emotional brain”</p>

Question 9

<p>Hypothalamus</p>

Answer 9

<p>Plays an important role in the nervous and endocrine systems. The hypothalamus appears to play a role in regulation of body temperature and circadian rhythms. eating behaviours, and parental attachment</p>

Question 10

<p>Amygdala</p>

Answer 10

<p>This part of the brain is believed to play a key role in emotion and memory consolidation. In addition, there is evidence that it plays a role in fear, aggression, sexual orientation, and trust</p>

Question 11

SAQ Intro LoF

Answer 11

• LoF is the theory that certain areas of the brain correspond to certain functions
• Refers to the idea that behaviour, emotions and thoughts originate in the brian in specific locations
• Different parts of the brain are responsible for different tasks, f.e. 2 main hemispheres
  - Left - logic, problem-solving
  - Right - creativity and imagination
  4 main lobes, occipital (vision), parietal (higher senses and language), frontal (reasoning and creativity) and temporal (hearing, perception and memory).
