Here, the authors show that sounds repeatedly delivered from the same spatial location evoke long-lasting neural facilitation and membrane potential depolarization in marmoset auditory cortex.doi:10.1038/s41467-025-58034-8Chen, ChenggangXu, Sheng
‘Auditory cortex’ is defined as the array of cortical areas that receives its principal thalamic input from either the ventral (MGv) or dorsal (MGd) divisions of the medial geniculate complex (MGC) (see Shared Features of the Auditory System of Birds and Mammals, Specialization of the Neocor...
Neurons in the auditory cortex exhibit distinct frequency tuning to the onset and offset of sounds, but the cause and significance of ON and OFF receptive field (RF) organisation are not understood. Here we demonstrate that distinct ON and OFF frequency
it is generally believed that the sensory inputs from CS such as a tone or flash of light are processed in the cortex10and are then transmitted to the amygdaloid complex, where the association between CS and US occurs11. Outputs from the central nucleus of the amygdala then project to the...

Auditory responses in the cortex ofPhyllostomus discolor As shown in Fig.1A, units responding to acoustic stimuli are found at parieto-temporal portions of the neocortex ofP. discolor. The distribution of neurophysiological recording sites defines the functional location of the bat's AC. External ...
Introduction The organization of the human auditory cortex has been described to be parcelled into more than 12 areas organized in 3 regions : the core line region, containing the primary auditory cortex (PAC) in the most anterior Heschl gyrus (HG or H1), surrounded by the belt region, itse...
In both stimulus conditions, the 100-ms response (N100m) decreased in latency and increased in amplitude as a function of intensity in both hemispheres. No systematic dependence was found between stimulus intensity and the NlOOm source location in the auditory cortex. Our study illustrates a non...
However, constituting the only signal input to the cortex, the nerve-firing patterns must contain all the information relevant for recognition. Therefore, an auditory-based featureextraction 1057–7130/98$10.00 © 1998 IEEE KUMAR et al.: ANALOG VLSI CHIP WITH ASYNCHRONOUS INTERFACE 601 ...
and relevance are given to the stimulus. Such higher-order functions originate from many regions of the brain—eg, prefrontal cortex, hippocampus, nucleus basalis of Meynert, and limbic circuits—that have either direct or indirect connections with each other and the auditory cortex.[16][17][18...
