[HTML][HTML] Rapid dopamine dynamics in the accumbens core and shell: learning and action

MP Saddoris, JA Sugam, F Cacciapaglia… - Frontiers in bioscience …, 2013 - ncbi.nlm.nih.gov
The catecholamine dopamine (DA) has been implicated in a host of neural processes as
diverse as schizophrenia, parkinsonism and reward encoding. Importantly, these distinct …

[PDF][PDF] Encoding predicted outcome and acquired value in orbitofrontal cortex during cue sampling depends upon input from basolateral amygdala

G Schoenbaum, B Setlow, MP Saddoris, M Gallagher - Neuron, 2003 - cell.com
Certain goal-directed behaviors depend critically upon interactions between orbitofrontal
cortex (OFC) and basolateral amygdala (ABL). Here we describe direct neurophysiological …

Different roles for orbitofrontal cortex and basolateral amygdala in a reinforcer devaluation task

CL Pickens, MP Saddoris, B Setlow… - Journal of …, 2003 - Soc Neuroscience
The orbitofrontal cortex (OFC) and basolateral amygdala (BLA) are critical for using learned
representations of outcomes to guide behavior. Neurophysiological findings suggest …

Orbitofrontal lesions in rats impair reversal but not acquisition of go, no-go odor discriminations

G Schoenbaum, SL Nugent, MP Saddoris, B Setlow - Neuroreport, 2002 - journals.lww.com
Recent evidence suggests that orbitofrontal cortex lesions cause an inability to withhold
inappropriate responses particularly when learned behavior must be modified to reflect changes …

Lesions of orbitofrontal cortex and basolateral amygdala complex disrupt acquisition of odor-guided discriminations and reversals

…, B Setlow, SL Nugent, MP Saddoris… - Learning & …, 2003 - learnmem.cshlp.org
Recent work indicates that both orbitofrontal cortex (OFC) and the basolateral complex of
the amygdala (ABL) are involved in processes by which cues are associated with predicted …

Corticohippocampal contributions to spatial and contextual learning

RD Burwell, MP Saddoris, DJ Bucci… - Journal of …, 2004 - Soc Neuroscience
Spatial and contextual learning are considered to be dependent on the hippocampus, but the
extent to which other structures in the medial temporal lobe memory system support these …

[HTML][HTML] Rapid associative encoding in basolateral amygdala depends on connections with orbitofrontal cortex

MP Saddoris, M Gallagher, G Schoenbaum - Neuron, 2005 - cell.com
Certain goal-directed behaviors depend upon interactions between basolateral amygdala (ABL)
and orbitofrontal cortex (OFC). Here we describe neurophysiological evidence of this …

Differential dopamine release dynamics in the nucleus accumbens core and shell reveal complementary signals for error prediction and incentive motivation

MP Saddoris, F Cacciapaglia… - Journal of …, 2015 - Soc Neuroscience
Mesolimbic dopamine (DA) is phasically released during appetitive behaviors, though there
is substantive disagreement about the specific purpose of these DA signals. For example, …

Orbitofrontal lesions impair use of cue-outcome associations in a devaluation task.

CL Pickens, MP Saddoris, M Gallagher… - Behavioral …, 2005 - psycnet.apa.org
Saddoris contributed equally to this work. This research was supported by National Institute

Cocaine‐experienced rats exhibit learning deficits in a task sensitive to orbitofrontal cortex lesions

G Schoenbaum, MP Saddoris… - European Journal of …, 2004 - Wiley Online Library
Addictive drugs, such as cocaine, cause long‐lasting neural changes in prefrontal cortex. It
has been hypothesized that these changes affect the behavioural control mediated by …
