Excitatory makes a neuron more likely to fire
Inhibitory, makes a neuron less likely to fire
Associate with neural addictive behavior. Movement leasage
Primary inhibitory NT in brain
- Primary exciting NT
- Ach- Acetylcholine neuromuscular junction
Steps involved in neurotransmission
- Nt Synthesis and storage into vessicle
- AP arrives
- Opnes Ca+ channels (voltage-gated) exocytosis (synaptic vessicles migrate toward the presypnatic membrane fuse with it and spill nt into synapse.
- Nt binds to receptor cites on postsynpatic membrane
- NT degraded (broken down) or recycled by sending neuron - reuptake.
Help (facilitate) NT effect e.g Alcohol + Gaba
Block or inhibit the NT effect e.g. botox + Ach.
associated with ligand activated ion channels. Fast, but shorter lived
a middle man takes it longer lasting
Structure- radiation and cheap
Structure - Stroke, blood brain barrier. Anurism, causes a stroke
Structure - Radiation and Cheap
Structures - Best for image quality - no radiation highlight/capitalize. Hydrogen can pick up cancer and tumors.
Function - Inject radio active substance. (Glucose - primary food source) more active in the brain is the more glucose it'll use. Look at the amount of glucose it uses. Specif structure. Radioactive. Relationship between structures and function. Correlation and causation. association related.
Function - Provides images of brain structure and activity. Cognitive neuroscience (studies human brain science). No radiation and functions.
Function - Transcriber - magnetic stimulation. Deactivates part of the brain.
Function - Used in sleep studies and epilepsy. record brain waves. Collects all action potential. Frequency
Keep an animals head in place
Mean destroying or removing brain tissues. Aspiration, Radio-frequency lesion, knife cut, cryogenic blockade.
