READ: They key to large-scale communication in the entire nervous system is the ability to pass nerve
impulses on a small scale from one neuron to the next so that signals can be transmitted throughout the
entire body. The junction between two neurons is called a synapse, and is the critical space that mediates
the transfer of a signal from the presynaptic neuron (the sender) to the postsynaptic neuron (the receiver)
or even an effector cell (like a gland or muscle cell.) You circled a synapse in Model 1. Synapses can be
electrical or chemical. Electrical synapses transmit electrical signals via gap junctions. A channel protein
connects the cytoplasm
of two adjacent neurons so that ions can flow directly from one cell to another to
pass on the signal. However, the most common type of synapse is a chemical synapse. These utilize
chemical signals, called neurotransmitters, to transmit the signal across the synaptic cleft. This is a
slower process, but allows for much greater precision…

(This should be dated, with a brief explanation of the studies) How do we study neurogenesis in animals? In humans? Where can we find stem cells in the brain? What is so important about these brain structures? (For example: Why do we find excess stem cells in these structures, but not in others?) How can stem cell proliferation be inhibited? How might neurogenesis be related to learning and memory?arrow_forwardb.

Neurotransmitters act on proteins called (2) _______________, which are found on cell membranes in synapses. (3) _______________ are very narrow gaps (20–50 nm) between neurons allowing for chemical transmission via neurotransmitters. The binding of neurotransmitters to pre- and post-synaptic receptors results in changes in the polarization of the cell.
