Physiology and topography of neurons with multipeaked tuning curves in cat primary auditory cortex.
1. The physiology and topography of single neuron responses along the isofrequency domain of the middle- and high-frequency portions [characteristic frequencies (CFs) greater than 4 kHz] of the primary auditory cortex (AI) were investigated in the barbiturate-anesthetized cat. Single neurons were recorded at several locations along the extent of isofrequency contours, defined from initial multi...
متن کاملRole of Amygdala-Infralimbic Cortex Circuitry in Glucocorticoid-induced Facilitation of Auditory Fear Memory Extinction
Introduction: The basolateral amygdala (BLA) and infralimbic area (IL) of the medial prefrontal cortex (mPFC) are two interconnected brain structures that mediate both fear memory expression and extinction. Besides the well-known role of the BLA in the acquisition and expression of fear memory, projections from IL to BLA inhibit fear expression and have a critical role in fear extinction. Howev...
متن کاملFine frequency tuning in monkey auditory cortex and thalamus.
The frequency resolution of neurons throughout the ascending auditory pathway is important for understanding how sounds are processed. In many animal studies, the frequency tuning widths are about 1/5th octave wide in auditory nerve fibers and much wider in auditory cortex neurons. Psychophysical studies show that humans are capable of discriminating far finer frequency differences. A recent st...
متن کاملTitle: Fine Frequency Tuning in Monkey Auditory Cortex and Thalamus
23 The frequency resolution of auditory neurons throughout the ascending auditory pathway 24 is an important parameter for understanding how sounds are processed. It has been shown in 25 previous animal studies that the frequency tuning widths are about 1/5 octave wide in auditory 26 nerve fibers and much wider in auditory cortex neurons (Pickles, 1979; McLaughlin et al., 2008; 27 see Table 1)....
متن کاملNull Mutations in EphB Receptors Decrease Sharpness of Frequency Tuning in Primary Auditory Cortex
Primary auditory cortex (A1) exhibits a tonotopic representation of characteristic frequency (CF). The receptive field properties of A1 neurons emerge from a combination of thalamic inputs and intracortical connections. However, the mechanisms that guide growth of these inputs during development and shape receptive field properties remain largely unknown. We previously showed that Eph family pr...
