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 communicate at structures called synapses in a process called synaptic transmission. The synapse consists of the two neurons, one of which is sending information to the other. The sending neuron is known as the pre-synaptic neuron (i.e. before the synapse) while the receiving neuron is known as the post-synaptic neuron (i.e. after the synapse). Although the flow of information around the brain is achieved by electrical activity, communication between neurons is a chemical process.
