Modelling novelty detection in the thalamocortical loop
Fig 11
Dependence of deviance-detecting effect and thalamic response patterns on the cortico-thalamic and intra-thalamic connection strength.
(A) Three late oscillation patterns (regimes) of thalamocortical cells can be elicited by a whisker deflection (marked in red under the time axis). (B-D) Sensitivity of SSA and true deviance detection in L4, L6 and thalamus to the strength of cortico-thalamic coupling on RE cells, , given different TC-to-RE synaptic conductances,
. Background colors denote one of the three regimes depicted in (A). (E) Analogous to (B-D), but by changing TC-to-RE synaptic conductances,
, with cortico-thalamic coupling strength,
, fixed. The starred value denotes the parameter’s default value.
