Tetrode recordings from auditory cortex - 629146_2018-04-20

Tetrode recordings from auditory cortex. During recordings, the animal was allowed to freely move within a 11x21 cm cardboard enclosure, with one wall consisting of an acoustically-transparent mesh panel to allow unobstructed sound stimulation. Pure tones were generated using MATLAB, and played via a digital signal processor. Pure tones of a duration of 200ms (including 5 ms linear rise and fall times) of variable frequencies (4-64 kHz in 0.1 octave increments) were used for stimulation.
