Document Summary

The senses and how the senses shape human perception. Within psychology, there are confounds; what might someone be manipulating: note that these confounds are experimental manipulations. The human consciousness is a multi-level process: neurochemical/cellular: neurotransmitters and neurons within the brain, neuroanatomical: the operation of major brain structures and their organization, physiological: substantial contributions from physiological systems beyond the brain. E. g. central nervous system (cns), hormones, bodily uids, etc. Socially speaking, our brains our affected by our respective social realms: while society is not in neurochemistry, it has in uences there. Environmentally speaking, different learning environments potentially have a profound effect on how people perceive reality: in short, physical environments can affect one"s neurochemistry and thus one"s consciousness. Dendrites are nerve endings which receive information from other neurons and transmit this information into the cell body. These dendrites can send either excitatory or inhibitory signals.
