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.
Neurons have a membrane that is designed to send information to other cells. The axon and dendrites are specialized structures designed to transmit and receive information. The connections between cells are known as synapses. Neurons release chemicals known as neurotransmitters into these synapses to communicate with other neurons. The Structure of a Neuron There are three basic parts of a neuron: the dendrites, the cell body, and the axon.
