Study Notes
Neurotransmitters and Functions
- Acetylcholine plays a crucial role in initiating voluntary muscle movement.
- Serotonin and dopamine are other significant neurotransmitters but do not primarily initiate muscle movement.
Brain Regions and Language
- Broca's area is essential for speech production; damage here leads to difficulty in speaking.
- Wernicke's area is important for language comprehension, whereas angular gyrus is involved in reading and writing.
Brain Function Localization
- Lateralization refers to the specialization of functions in either the right or left hemisphere of the brain, such as speech.
Sensory Processing
- The sensory cortex is critically involved in processing touch sensations; it integrates information from various sensory modalities.
Neuron Structure
- Axons are the longest part of a neuron, responsible for transmitting messages to leg muscles and other distant targets.
Nervous System Responses
- The parasympathetic nervous system regulates rest and recuperation, decreasing heart rate and blood pressure during calming situations.
Neurotransmitter Dynamics
- Reuptake is the process through which excess neurotransmitter molecules are reabsorbed by the sending neuron, essential for regulating neurotransmission.
Brain Activity Measurement
- An EEG (electroencephalogram) provides an amplified recording of electrical activity across the brain's surface, useful for diagnosing various conditions.
Synaptic Connections
- A synapse is a junction between a sending neuron and a receiving neuron, facilitating communication through chemical signals.
Mental Health Disorders
- An undersupply of serotonin is closely linked to depression, highlighting the importance of this neurotransmitter in mood regulation.
