Deviance detection in auditory subcortical structures: what can we learn from neurochemistry and neural connectivity?

Abstract: A remarkable ability of animals that is critical for survival is to detect and respond to to unexpected stimuli in an ever-changing world. Auditory neurons that show stimulus-specific adaptation (SSA), i.e., a decrease in their response to frequently occurring stimuli while maintaining responsiveness when different stimuli are presented, might participate in the coding of deviance occurrence. Traditionally, deviance detection is measured by the mismatch negativity (MMN) potential in studies of evoked local fie… Show more

“…Our fMRI data show that cortical change-induced activity was accompanied by substantial subcortical activations, covering large portions of the thalamus as well as parts of the superior and inferior colliculi. These findings agree with previous studies reporting deviance-related processing at subcortical level, in particular in the inferior colliculus and the medial geniculate nucleus of the thalamus [Antunes and Malmierca, 2014;Cacciaglia et al, 2015;Duque et al, 2015;Mitchell et al, 2015;Slabu et al, 2012]. In animals, subcortical effects have been shown to occur earlier than on the cortical level, but to be modulated by corticofugal auditory cortex projections [Antunes and Malmierca, 2014;Antunes et al, 2010;Malmierca et al, 2009].…”

“…In addition to the convergence of depressing synapses that convey frequency-specific inputs, our model also incorporates surrounding inhibition. Broadly tuned neurons exhibited more extensive suppression and larger SSA strength (Figure 5 ), which is consistent with the stronger SSA found in the non-lemniscal pathway in which neurons have broader tunings (Malmierca et al, 2009 ; Duque et al, 2012 , 2015 ; Ayala and Malmierca, 2013 ; Ayala et al, 2015b ). This result implies that broadly tuned neurons might undergo more prominent adaptation due to broader convergence of inputs, including those from the CNIC or cortical feedback that cannot be fully covered by the present model (Ayala et al, 2015b ).…”

“…It is not generated by the corticocollicular projection through top-down modulation (Anderson and Malmierca, 2013 ; Malmierca et al, 2015 ). The predictive power of our model suggests that frequency-specific adaptation may be generated via a feedforward network, employing synaptic depression (Duque et al, 2015 ) of the afferents either from CNIC to cortical IC neurons or from a lower nucleus to CNIC. It is a variant of the adaptation of narrowly tuned modules (ANTM) model (Nelken, 2014 ), which was proposed previously (Mill et al, 2011a , b , 2012 ; Taaseh et al, 2011 ; Hershenhoren et al, 2014 ).…”

“…Hence, multiple excitatory, inhibitory and modulatory inputs converge onto single IC neurons (Ito & Oliver, 2010 that also receive neuromodulatory inputs from multiple sources (for a review, see Duque, Ayala, & Malmierca, 2015).…”
