Fill In: (1-2 pts each)
Neurotransmitters are generally stored in _____________ __________________. After release,

transmitters diffuse across the _____________ _____________ and bind to________________ on

the ___________________ membrane. This binding results in the opening of ______________-gated

_____________ and either an EPSP or an IPSP is produced. EPSPs are typically due to the

influx/efflux of ________________ ions. IPSPs are typically due to the influx/efflux of

____________________ ions. (circle influx or efflux!)

A split-brain patient is shown a picture of a woman talking on a telephone. The picture is shown briefly in her left visual field. When asked what she saw, she could only say that she saw a woman. When asked what the woman was doing, the patient was confused and guessed that the woman was skipping rope. However, the patient could write the answer “telephone” using her left hand. Explain the basis of this phenomenon. (6 pts)
