Neuromodulator Dynamics Underlying Associative Learning in the Ventral Striatum's Olfactory Tubercle

open access: yesAdvanced Science, EarlyView.
Using fiber photometry and genetically encoded sensors, the dynamic release patterns of four neuromodulators in the olfactory tubercle (OT)—a brain region overlapping with the olfactory cortex and ventral striatum—were systematically monitored in response to external rewards and distinct reward‐associated learning processes.

Nucleus accumbens deep brain stimulation in adult patients suffering from severe and enduring anorexia nervosa (STIMARS): protocol for a pilot study

open access: yesFrontiers in Psychiatry
BackgroundAffecting adolescent and young adults, anorexia nervosa (AN) has the highest death rate of all mental disorders. Effective treatment options are lacking and a significant proportion of patients develop severe and chronic forms of the disease ...

Adeno-associated virus (AAV)-mediated suppression of Ca2+/calmodulin kinase IV activity in the nucleus accumbens modulates emotional behaviour in mice

open access: yesBMC Neuroscience, 2007
Background Calcium/calmodulin-dependent protein kinase IV (CaMKIV) controls activity-dependent gene transcription by regulating the activity of the cyclic AMP response element binding protein (CREB). This signaling pathway is involved in gating emotional

Food-induced behavioral sensitization, its cross-sensitization to cocaine and morphine, pharmacological blockade, and effect on food intake [PDF]

open access: yes, 2006
Repeated administration of abused drugs sensitizes their stimulant effects and results in a drug-paired environment eliciting conditioned activity. We tested whether food induces similar effects.

The bivalent side of the nucleus accumbens [PDF]

open access: yesNeuroImage, 2009
An increasing body of evidence suggests that the nucleus accumbens (NAcc) is engaged in both incentive reward processes and in adaptive responses to conditioned and unconditioned aversive stimuli. Yet, it has been argued that NAcc activation to aversive stimuli may be a consequence of the rewarding effects of their termination, i.e., relief. To address

Foreign Language Learning in Older Adults Modifies Resting‐State Functional Connectivity Between the Subcortical Structures and the Cortex

open access: yesAGING MEDICINE, EarlyView.
Foreign language learning in older adults reorganizes thalamic and caudate connectivity, in a process topographically overlapping with the expression of receptors and genes related to neuroplasticity. ABSTRACT Objectives Neuroimaging studies suggest that Foreign Language Learning (FLL) influences resting‐state functional connectivity (rs‐FC) within the

Is Deep Brain Stimulation a viable treatment for substance-related addiction? [PDF]

open access: yesRomanian Journal of Neurology, 2019
For the ability to modulate the activity of dysregulated networks Deep Brain Stimulation (DBS) of areas involved in reward system and motivational states may have a potential application in addiction despite risks associated with its invasiveness.

Differential Behavioral Responses to\ud Cocaethylene of Long-Evans and\ud Sprague-Dawley Rats: Role of Serotonin [PDF]

open access: yes, 1997
Cocaethylene is a neuroactive metabolite derived from the concurrent consumption of cocaine and ethanol. The effects of cocaethylene on locomotor activity, stereotypy, and rearing in Long-Evans and Sprague-Dawley rats were compared.A single cocaine ...

The Nucleus Accumbens and Pavlovian Reward Learning [PDF]

open access: yesThe Neuroscientist, 2007
The ability to form associations between predictive environmental events and rewarding outcomes is a fundamental aspect of learned behavior. This apparently simple ability likely requires complex neural processing evolved to identify, seek, and use natural rewards and redirect these activities based on updated sensory information.
