Basis of figuring out key to neuronal communication was chemical messages (nt)
Acetylcholine
-
Same chemicals in the rest of the body slower than hormones
-
Vehicle
Post/pre synampic membrane where they are
4 steps of neurotransmitssio
4 steps of the release of neurotransmiters
Neurotransmitter don't go in the bind to recptor site - depolarize or hyperpolarize
Activation of receptors
Once it's in the synapses activation mechanism
Type 1 excitatory
Type 2 inhibitory
How they look
How to identify criteria of becoming/called a neurotransmiters
Small molecule (quick acting) synth by diet
Peptides
Gases
Broke the neurotransmitter down in 3 groups (
How acetylcholine is formed how it's broken down (from enzyme or protein)
Rate limiting factor - can't eat all the bananas (proteins that are available)
Peptide transmitters/gases ( don't need to focus
Ionotropic - more direct at binding site
Metabatropic - G protein; second messengers; cascade effect
Two types of receptors postsunaptic (properties of each)
Inhibitory in some parts
Cholinergic - neurons leaving spinal cord
Somatic
How neurotransmitter can have diffenrent effect depending on what system
Neurotransmitter how they are the power supply to Brain; cell body's in brain
stem projects to the rest of the brain
Central ns - behaviour
Activist system
Alzheimer's
Schizophrenia - dopemenergic system
Noreneric/ sertotinergic system
Terminology
-
-discovery of neurotransmiters
reduced neurotransmitter realaes
Habitation
Sensitization
On a molecular how does that look
Basic learning
Long term potentiation and how it works - mechanism
Conditioning
Implicit
Explicit
Memory
