Brain and Behavior Exam Flashcards

What do astrocytes do for the cell?

Astrocytes monitor neuron activity.

Where are Schwann cells located?

Schwann Cells are located in the PNS.

What type of neurotransmitter does the Sympathetic Nervous System contain?

Norepinephrine/Pre-ganglionic Neurons

What type of neurotransmitter does the Parasympathetic Nervous System contain?

Acetylcholine

Forebrain -Telencephalon - Basal Ganglia (PCGS)

Motor Control

Forebrain - Diencephalon - Thalamus (HAMS); Where is it located?

It is located between the cerebral cortex and the brainstem.

Intracellular Pathway

Water-soluble molecules

Trans-cellular Pathway

Lipid-soluble

What are ions dissolved in?

Intracellular Fluid

What does electrostatic pressure do?

It causes ions to flow towards oppositely charged areas.

Where are Nicotinic ACh receptors?

Muscles

Where are the Muscarinic ACh receptors?

Brain

What is the difference between Ionotropic and Metabotropic Receptors?

Ionotropic receptors are much faster and they change shape when receptors bind to them, whereas metabotropic receptors are much slower and require a g-protein to let ions through.

What drugs enhance GABA function?

Benzodiazepines

Dopamine

• Substantia Nigra - Parkinson’s Disease

• Ventral Tegmental - Reward; Schizophrenia/Depression

Where is Norepinephrine synthesized? What drug blocks it?

Locus Coeruleus/Pons; Propanolol

Where is Serotonin synthesized?

Raphe Nuclei
