Lesions restricted to structures on one half of the brain are called
Unilateral lesions
Lesions restricted to structures on one half of the brain usually have effects that are much less severe than do comparable
Bilateral lesions
Intracellular unit recording is particularly difficult in
Freely moving animals
Unlike other electrophysiological methods of recording neural activity, intracellular unit recording provides measurements of
The membrane potential
Extracellular unit recording provides information about A) the magnitude of the membrane potential B) the wave form of action potentials C) EPSPs
None of the above
Multiple-unit signals are typically A) recorded through microelectrodes B) recorded through electrodes that are larger than microelectrodes C) integrated, or added together, to facilitate their interpretation
Both B and C
