Study Notes
Neurotransmitters and Brain Function
- GABA (Gamma-Aminobutyric Acid) is the primary inhibitory neurotransmitter in the central nervous system, regulating neuronal excitability and reducing anxiety.
- Norepinephrine stimulates the sympathetic nervous system, preparing the body for "fight or flight" responses.
- Serotonin regulates appetite and energy balance, influencing food intake, satiety, and metabolism.
- Dopamine is involved in motor control, reward, and motivation.
Brain Structures and Functions
- The cerebellum is responsible for coordinating voluntary movements, balance, posture, and motor learning.
- The hypothalamus regulates various physiological processes, including hormone release via the pituitary gland.
- The amygdala is involved in emotional responses, particularly fear and aggression.
- The hippocampus is responsible for the formation of long-term memories.
Pharmacology
- Anticonvulsants are used to treat epilepsy by enhancing the effects of GABA.
- Benzodiazepines are a class of anxiolytic drugs that enhance the inhibitory effects of GABA, reducing anxiety and promoting relaxation.
- Antipsychotics are used to treat schizophrenia by blocking dopamine receptors.
- Tricyclic antidepressants (TCAs) are a class of medications used to treat depression.
- Selective serotonin reuptake inhibitors (SSRIs) work by selectively inhibiting the reuptake of serotonin, increasing its concentration in the synaptic cleft and enhancing neurotransmission.
Diseases and Disorders
- Alzheimer's disease is characterized by a deficiency in acetylcholine, a neurotransmitter involved in memory and learning.
- Parkinson's disease is associated with a deficiency of dopamine in the brain, leading to motor symptoms such as tremors and rigidity.
- Schizophrenia involves a hyperactive dopaminergic system, leading to symptoms such as hallucinations, delusions, and disorganized thinking.
