Confocal analysis of cholinergic and dopaminergic inputs onto pyramidal cells in the prefrontal cortex of rodents

open access: yesFrontiers in Neuroanatomy, 2010
Cholinergic and dopaminergic projections to the rat medial prefrontal cortex (mPFC) are both involved in cognitive functions including attention. These neuronal systems modulate mPFC neuronal activity mainly through diffuse transmission.

Creativity and Delusions: A Neurocomputational Approach [PDF]

open access: yesarXiv, 2000
Thinking is one of the most interesting mental processes. Its complexity is sometimes simplified and its different manifestations are classified into normal and abnormal, like the delusional and disorganized thought or the creative one. The boundaries between these facets of thinking are fuzzy causing difficulties in medical, academic, and ...

Multi‐Omics and ‐Organ Insights into Energy Metabolic Adaptations in Early Sepsis Onset

open access: yesAdvanced Science, EarlyView.
This study shows that patients at risk of sepsis have a distinct metabolite and lipid signature, including serine and aminoadipic acid, in their serum before clinical diagnosis. A mouse model of sepsis with a compatible serum signature reveals underlying metabolic changes, including mitochondrial adaptation, altered serine‐dependent purine metabolism ...

Efficient conversion of astrocytes to functional midbrain dopaminergic neurons using a single polycistronic vector.

open access: yesPLoS ONE, 2011
Direct cellular reprogramming is a powerful new tool for regenerative medicine. In efforts to understand and treat Parkinson's Disease (PD), which is marked by the degeneration of dopaminergic neurons in the midbrain, direct reprogramming provides a ...

A Computational Model of the Effects of Drug Addiction on Neural Population Dynamics [PDF]

open access: yesarXiv, 2012
Reward processing and derangements thereof, such as drug addiction, involve the coordinated activity of many brain areas. Prior work has identified many behavioral, molecular biological and single neuron changes throughout the mesocorticolimbic system that reflect and drive addictive behavior.

Visualization of the Spiral Ganglion Neuron in Vivo Using a Novel 177Lu Nuclear Molecule Label

open access: yesAdvanced Science, EarlyView.
The study developed and validated a radionuclide‐labeled anti‐VGLUT1 antibody probe for the first nuclear imaging of cochlear spiral ganglion neurons (SGNs) in vivo. This approach may provide aid in screening candidates suitable for CI surgery by quantifying the number of surviving SGNs, and predicting the potential for postoperative hearing ...

Proteolytic activation of proapoptotic kinase protein kinase Cδ by tumor necrosis factor α death receptor signaling in dopaminergic neurons during neuroinflammation

open access: yesJournal of Neuroinflammation, 2012
Background The mechanisms of progressive dopaminergic neuronal loss in Parkinson’s disease (PD) remain poorly understood, largely due to the complex etiology and multifactorial nature of disease pathogenesis.

Reinforcement Learning in a Neurally Controlled Robot Using Dopamine Modulated STDP [PDF]

open access: yesarXiv, 2015
Recent work has shown that dopamine-modulated STDP can solve many of the issues associated with reinforcement learning, such as the distal reward problem. Spiking neural networks provide a useful technique in implementing reinforcement learning in an embodied context as they can deal with continuous parameter spaces and as such are better at ...

Antidepressant-like Effects of Neuropeptide SF (NPSF) [PDF]

open access: yesWorld Journal of Research and Review (WJRR) ISSN:2455-3956, Volume-4, Issue-5, May 2017 Pages 26-30, 2020
Neuropeptide SF (NPSF) is a member of RFamide neuropeptides that play diverse roles in central nervous system. Little is know about the effects of NPSF on brain functions. Antidepressant-like effect of NPSF was studied in modified mice FST. NPSF showed the antidepressant-like effects by decreasing the immobility time and increasing the climbing and ...

Dopaminergic neurons promote hippocampal reactivation and spatial memory persistence

open access: yesNature Neuroscience, 2014
We found that optogenetic burst stimulation of hippocampal dopaminergic fibers from midbrain neurons in mice exploring novel environments enhanced the reactivation of pyramidal cell assemblies during subsequent sleep/rest.
