Spatial sensitivity in field PAF of cat auditory cortex.
We compared the spatial tuning properties of neurons in two fields [primary auditory cortex (A1) and posterior auditory field (PAF)] of cat auditory cortex. Broadband noise bursts of 80-ms duration were presented from loudspeakers throughout 360 degrees in the horizontal plane (azimuth) or 260 degrees in the vertical median plane (elevation). Sound levels varied from 20 to 40 dB above units' th...
متن کاملFunctional networks of parvalbumin-immunoreactive neurons in cat auditory cortex.
Inhibitory interneurons constitute ∼20% of auditory cortical cells and are essential for shaping sensory processing. Connectivity patterns of interneurons in relation to functional organization principles are not well understood. We contrasted the connection patterns of parvalbumin-immunoreactive cells in two functionally distinct cortical regions: the tonotopic, narrowly frequency-tuned module...
متن کاملIntracellular characterization of suppressive responses in supragranular pyramidal neurons of cat primary auditory cortex in vivo.
Several suppressive processes shape the response properties of auditory neurons, namely lateral inhibition, non-monotonic rate level function and excitation/inhibition binaural interaction. By combining intracellular recording from and staining of layers 2 and 3 pyramidal neurons (PNs) in cat primary auditory cortex, we demonstrate the temporal aspects of depolarization and hyperpolarization un...
متن کاملResponses of neurons in primary auditory cortex (A1) to pure tones in the halothane-anesthetized cat.
The responses of primary auditory cortex (A1) neurons to pure tones in anesthetized animals are usually described as having mostly narrow, unimodal frequency tuning and phasic responses. Thus A1 neurons are believed not to carry much information about pure tones beyond sound onset. In awake cats, however, tuning may be wider and responses may have substantially longer duration. Here we analyze ...
متن کاملModulation of level response areas and stimulus selectivity of neurons in cat primary auditory cortex.
Sounds commonly occur in sequences, such as in speech. It is therefore important to understand how the occurrence of one sound affects the response to a subsequent sound. We approached this question by determining how a conditioning stimulus alters the response areas of single neurons in the primary auditory cortex (AI) of barbiturate-anesthetized cats. The response areas consisted of responses...
