Study Notes

Brain Functions

The brain is crucial for emotional feelings, voluntary movements, learning, memory, and thinking.
The spinal cord extends from the medulla oblongata at the brain's base to the upper two-thirds of the spine, approximately in the lower back.
The spinal cord is roughly the thickness of a pinky finger.

Processes in Neurotransmission

Precursors: Involve acquiring raw materials necessary for neurotransmitter synthesis.
Biosynthesis: The process of producing neurotransmitters.
Storage: Neurotransmitters are stored in vesicles within Golgi bodies.
Transport: Neurofilaments and microtubules facilitate the movement of neurotransmitters within neurons.
Docking and Influx of Ca++: Vesicles dock at the presynaptic membrane, and calcium ions flow in, triggering release.
Exocytosis: The fusion of vesicles with the membrane leading to neurotransmitter release into the synaptic gap.
Binding: Neurotransmitters bind to postsynaptic receptors on the neighboring neuron.
Reuptake Mechanisms: Mechanisms in place to recover neurotransmitters for reuse.
Deactivation: The process that ensures neurotransmitters are rendered inactive after their role is completed.

Categories of Neurotransmitters (NTs)

Amino Acids: Includes neurotransmitters such as:
- Glutamate (Glu)
- GABA (gamma-aminobutyric acid)
Biogenic Amines:
- Acetylcholine (Ach)
- Monoamines including catecholamines like:
  - Dopamine (DA)
  - Norepinephrine (NE)
- Indolamines, notably serotonin (5-HT)
Neuropeptides:
- Opioid peptides that include:
  - Enkephalins
  - Endorphins
  - Dynorphins

REM Sleep

REM sleep is identified by decreased EEG amplitude, muscle atonia (loss of muscle tone), varying autonomic responses, and rapid eye movement episodes.
It encompasses two components: tonic (sustained) and phasic (rapid bursts) aspects.
