EOG recordings and cookie-finding tests of intraperitoneally (IP) MPTP injected animals.

EOG data from mice injected with MPTP intraperitoneally (A) two days (2d) and (B) five days (5d) after treatment. The amplitudes of the responses, the rise, and the decay times did not differ significantly between the groups. nIP = 5 animals per condition. (C) Cookie-finding tests after 5 days of IP MPTP injection showed no significant difference between saline and MPTP treated animals (n = 10 per condition). BAsyn animals took significantly longer to find the cookie. (D) Animal mobility (mean movement velocity) during the cookie-finding test. BAsyn animals display a significantly reduced mobility. Error bars represent SEM.
