Higher death rates. Today's scientists point to climate change as the biggest global health threat of the 21st century.. It's a threat that impacts all of usâespecially children, the elderly, low-income communities, and minoritiesâand in a variety of direct and indirect ways. As temperatures spike, so does the incidence of illness, emergency room visits, and death.
The presynaptic neuron is the neuron whose axon forms a synapse with the dendrite of another neuron. The presynaptic neuron sends out information. The postsynaptic neuron is the neuron whose dendrite forms a synapse with the axon of the presynaptic neuron. The postsynaptic neuron receives information.ommunication between neurons is the foundation for brain function. Understanding how neurotransmission occurs is crucial to understanding how the brain processes and integrates information. Interruption of neural communication causes changes in cognitive processes and behavior.
a slender branching process that extends from the cell body of a neuron and that is capable of being stimulated by a neurotransmitter. Each neuron usually possesses several dendrites, which receive synapses where chemical transmission occurs from axons to dendrites (or an axon, in the case of unipolar neurons).The number of dendrites and thus the number of synapses varies with the functions of a neuron. Also called cytodendrite. Compare axon.ach neuron usually possesses several dendrites, which receive synapses where chemical transmission occurs from axons to dendrites (or an axon, in the case of unipolar neurons).
