Study Guide for PSY 364- Behavioral Neuroscience Final Exam Fall 2023

Behavioral Neuroscience

The study of the biological basis of behavior, focusing on the brain and nervous system.

Western Blotting

A technique used to separate proteins by size and detect them using antibodies.

High-Performance Liquid Chromatography (HPLC)

A technique for measuring neurotransmitter concentrations by separating components in a liquid.

Soma (Cell Body)

The part of a neuron that contains the nucleus and organelles.

Resting Potential

The electrical potential of a neuron when it is not actively transmitting a signal, typically around -70 mV.

Saltatory Conduction

The process of action potentials 'jumping' between nodes of Ranvier in myelinated axons, increasing conduction speed.

Phospholipid Bilayer

A semi-permeable barrier forming the cell membrane of neurons.

Ionotropic Receptors

Fast-acting receptors that are ligand-gated ion channels.

Metabotropic Receptors

Slow receptors that operate through G-protein-coupled mechanisms.

Synaptic Vesicles

Membrane-bound sacs in the presynaptic terminal that contain neurotransmitters.

Reuptake

The process of neurotransmitters being taken back into the presynaptic neuron.

Dopamine

A neurotransmitter involved in motor control and reward processing, primarily found in the basal ganglia.

Schizophrenia Positive Symptoms

Symptoms include delusions and hallucinations.

ADHD Dopamine Dysfunction

An imbalance between the Default Mode Network and Task-On Network associated with attention deficits.

GABA

An inhibitory neurotransmitter found in the basal ganglia and cerebellum.

APA Ethical Principles

Guidelines ensuring participant well-being, fairness, and confidentiality in research.

Alzheimer's Disease Hallmarks

Characterized by β-amyloid plaques and tau tangles, primarily affecting the hippocampus.
