Biological basis of pratice Flashcards
What is epigenetics?
Study of mechanisms by which gene expression is modified without changes in organisms genetic sequence.
Population genetics?
Studies about family/twins/adoption. It’s possible that mental health disorders are polygenic.
True or false: Genetics are a risk factor in developing some mental health disorders like schizophrenia or depression
True
What is a comparative approach?
Compares behaviours with other life forms.
What’s a developmental approach?
Studies the nervous system structure across different stages of development
What is chemoarchitectural approach?
Identification of differences in location of neurotransmitters/chemicals throughout the brain
What’s cytoarchitectural approach?
Identifies differences/variations in cell type, structure, and density throughout brain.
What’s a functional approach to neuroanatomy?
Identifies location of predominant control over various behavioural functions within brain
What is neuroplasticity?
Ability of brain to change its structure/function in response to pressures (internal and external). It compensates for loss in a specific area. Nerve signals may be rerouted, cells learn new function, and nerve tissues may be generated.
Left and right hemispheres of the cerebrum/function?
Left- involved in verbal language functions and memory
Right- involved in non verbal communication
What do the 4 lobes of the brain do?
- Frontal- personality, insight/judgement, problem solving
- Temporal- auditory, olfactory areas
- Optical- vision
- Parietal- taste, touch
What is limbic system in charge of?
Involved in some of the basic emotions and memory .
Basal ganglia function?
Motor function so its affected in parkinson’s disease.
What are neurotransmitters?
Small molecules directly/indirectly responsible for opening an closing ion channels
Neuromodulators?
Chemical messengers that make cell membranes more or less susceptible to effects of primary neurotransmitters
