Lateral orbitofrontal neurons acquire responses to upshifted, downshifted, or blocked cues during unblocking
The lateral orbitofrontal cortex (lOFC) has been described as signaling either outcome expectancies or value. Previously, we used unblocking to show that lOFC neurons respond to a predictive cue signaling a 'valueless' change in outcome features (McDannald, 2014). However, many lOFC neurons also fired to a cue that simply signaled more reward. Here, we recorded lOFC neurons in a variant of this...
متن کاملOrbitofrontal neurons acquire responses to ‘valueless’ Pavlovian cues during unblocking
The orbitofrontal cortex (OFC) has been described as signaling outcome expectancies or value. Evidence for the latter comes from the studies showing that neural signals in the OFC correlate with value across features. Yet features can co-vary with value, and individual units may participate in multiple ensembles coding different features. Here we used unblocking to test whether OFC neurons woul...
متن کاملBackground firing rates of orbitofrontal neurons reflect specific characteristics of operant sessions and modulate phasic responses to reward-associated cues and behavior.
The orbitofrontal cortex plays an important role in the ability of animals to adjust their behavior in response to behavioral outcomes. Multiple studies have demonstrated that responses of orbitofrontal neurons during operant sessions reflect the outcome of particular behaviors. These studies have focused on rapid neural responses to short-duration events such as instrumental behavior and rewar...
متن کاملIncreased firing to cues that predict low-value reward in the medial orbitofrontal cortex.
Anatomical, imaging, and lesion work have suggested that medial and lateral aspects of orbitofrontal cortex (OFC) play different roles in reward-guided decision-making, yet few single-neuron recording studies have examined activity in more medial parts of the OFC (mOFC) making it difficult to fully assess its involvement in motivated behavior. Previously, we have shown that neurons in lateral p...
متن کاملHedonic and informational functions of the human orbitofrontal cortex.
Functional imaging studies have revealed roles for orbitofrontal cortex (OFC) in reward processing and decision making. In many situations, rewards signal that the current behavior should be maintained, whereas punishments cue a change in behavior. Thus, hedonic responses to reinforcers are conflated with their function as behavioral cues. In an attempt to disambiguate these functions, we perfo...
