The amygdala

Joseph LeDoux
2007 Current Biology  
The auditory input connections of the lateral amygdala have been studied most thoroughly. Auditory inputs reach the lateral amygdala from the auditory thalamus and auditory cortex.  ...  In addition, both the lateral and basal nuclei project to the intercalated cells which then connect with the central nucleus.  ...  We show by transplantation of small parts of the gastrula embryo that the blastopore lip -but not tissue from other parts of the embryo -is able to act as an organiser and to induce the formation of a  ...

Computational models of neurophysiological correlates of tinnitus

Roland Schaette, Richard Kempter
2012 Frontiers in Systems Neuroscience  
It is now clear that tinnitus is generated in the brain, not in the ear, and that it is correlated with pathologically altered spontaneous activity of neurons in the central auditory system.  ...  At the network level, lateral inhibition could amplify differences in spontaneous activity, and structural changes such as reorganization of tonotopic maps could lead to self-sustained activity in recurrently  ...  This work was supported by the British Tinnitus Association, by the Deutsche Forschungsgemeinschaft (DFG) through the SFB 618 "Theoretical Biology", and the Bundesministerium für Bildung und Forschung  ...

A sensitive period for cochlear implantation in deaf children

Anu Sharma, Julia Campbell
2011 Journal of Maternal-Fetal & Neonatal Medicine  
One way of examining the time limits for plasticity in the human central auditory system is the use of cortical auditory evoked potentials (CAEPs).  ...  This decrease in latency is a result of the refinement and maturation of the central auditory pathways as the system develops.  ...
