  <![CDATA[<p><strong>Abstract</strong></p>  <p>The first part of the prese
 ntation will focus on the bi-directional interaction between memory and de
 cision making. Decisions are guided by information stored in memory. I wil
 l present behavioural and fMRI data acquired during a second-order conditi
 oning (SOC) paradigm to provide evidence that\, during higher-order learni
 ng\, outcome-predictive conditioned stimuli reinstate the cortical represe
 ntations of the outcome with which they had previously been paired. This m
 ay allow transfer of motivational value to novel stimuli that had never be
 en directly paired with reinforcement. Next\, I will argue that the mere a
 ct of making a choice may in turn shape our associative memories. Simply c
 hoosing/not choosing an option from a pair (absent any outcome) was suffic
 ient to (i) increase/decrease choice probabilities compared to an otherwis
 e equally-valued alternative option and to (ii) strengthen/weaken hippocam
 pal stimulus-outcome associations.</p>  <p>The second part will address th
 e relationship between a measure of cortical excitation/inhibition (E/I) b
 alance and two different kinds of decision making. The decision of whether
  or not to incur a travel cost in order to abandon a depleting patch (in f
 avour of a better alternative) was related to E/I balance in dorsal anteri
 or cingulate cortex. In contrast\, simple reward-maximizing decisions were
  related to E/I balance in ventromedial prefrontal cortex.<br /> <br />
