Document Summary
Career opportunities: research positions typically require a phd in psychology, biology, or neuroscience. 1. 2: genetics and behavior: genetics play a major role in controlling facial expressions. Environmental modification: the effe(cid:272)t of so(cid:373)e ge(cid:374)es depe(cid:374)ds o(cid:374) the perso(cid:374)"s e(cid:374)(cid:448)iro(cid:374)(cid:373)e(cid:374)t, phenylketonuria (pku): genetic inability to metabolize phenylalanine, hereditary condition, but environmental interventions can modify it.

Anatomy of neurons and glia: neurons receive information and transmit it to other cells, the adult brain contains approx.

Variations among neurons: the shape of a neuron determines its connections with other neurons, neurons with wider branching connect with more targets and therefore can receive a huge number of inputs.
