Definition
Synapses are specialized junctions between neurons that facilitate communication by allowing the transmission of electrical or chemical signals. Neurotransmitters are chemical messengers released from the presynaptic neuron that bind to receptors on the postsynaptic neuron, thereby influencing its activity.
Summary
Synapses and neurotransmitters are fundamental components of the nervous system, enabling communication between neurons. Synapses serve as the connection points where neurotransmitters are released, allowing signals to be transmitted across the synaptic cleft. Understanding these processes is crucial for grasping how the brain functions and how various behaviors and emotions are regulated. Neurotransmitters, the chemical messengers, play diverse roles in influencing mood, cognition, and bodily functions. The balance between excitatory and inhibitory neurotransmitters is essential for maintaining proper brain function. Additionally, synaptic plasticity highlights the brain's ability to adapt and learn, making these concepts vital for students of biology and neuroscience.
