DESCRIPTION:Speaker: Anton Ilango Micheal\nAbstract: Excitation of midbrain
  dopamine (DA) neurons are known to be positively reinforcing. Suchreinfor
 cing signals are arising in the form of phasic bursts and both phasic and 
 tonic firingsupports eliciting and strengthening the learning relevant sig
 nals. While DA network isunified in eliciting reward\, various heterogenou
 s elements withinthe larger network reads the ongoing task relevant detail
 s and underlies the acquisition ofaction learning even under aversive cond
 itioning. In this talk\, I will summarise\,our work over the last several 
 years utilising optogenetic techniques in self-stimulation\,place preferen
 ce\, signaled active avoidance learning and blocking procedures.Briefly\, 
 similar role of substantia nigra (SNc) and ventral tegmental area (VTA) in
  elicitingreward and aversion\, impact of silencing VTA DA during predicti
 on and post diction of cuesignaledavoidance are presented as well. I will 
 also emphasize various analysis strategieswhen reading the behavioral meas
 urements coupled with temporally precise optogeneticperturbations.
