Neurotransmitters and Neural Communication
Neural communication occurs through an intricate network of neurons, with dendrites receiving and transmitting messages across synapses billions of times per second.
Definition: Neurotransmitters are chemical messengers that regulate various bodily functions and emotional responses.
The four primary neurotransmitters each serve distinct functions:
- Serotonin manages mood, sleep, and muscle control
- Dopamine controls reward pathways and cognition
- Norepinephrine (adrenaline) manages fight/flight responses
- These chemicals work in specific brain regions like the hypothalamus and amygdala
Highlight: The amygdala's response to adrenaline is crucial in stress reactions and emotional processing.
Example: Common substances like antidepressants and even social media likes can influence neurotransmitter levels and affect mood.
