Neuroanatomical and functional correlates in borderline personality disorder: A narrative review

Ibrain, Volume 11, Issue 1, Page 19-31, Spring 2025.
Borderline personality disorder (BPD) is considered a dysfunctional, stable, and pervasive alteration in personality functioning with the inability to adapt to the environment, mental rigidity, and ego‐syntonic, and like all personality disorders is a consistent pattern of inner experience and behavior that deviates markedly from the expectations of ...

Chronic hyperammonemia alters motor and neurochemical responses to activation of group i metabotropic glutamate receptors in the nucleus accumbens in rats in vivo

Neurobiology of Disease, 2003
Hyperammonemia leads to altered cerebral function and neurological alterations in patients with hepatic encephalopathy. We studied the effects of hyperammonemia in rats on the modulation by group I metabotropic glutamate receptors (mGluR) of motor and ...

Activity-based anorexia enhances glutamatergic synaptic transmission and neuronal excitability within the nucleus accumbens of female mice. [PDF]

Physiol Rep
Abstract Anorexia nervosa is a severe psychiatric disorder characterized by persistent food restriction and often excessive physical activity, implicating dysfunction in neural circuits governing motivation, reward, and behavioral persistence. The nucleus accumbens (NAc) is a central component of these circuits, yet synaptic and cellular adaptations ...

Dopaminergic novelty detection and theta oscillations: Virtual reality‐based adaptive interventions for cognitive enhancement in aging

Ibrain, EarlyView.
Aging‐related cognitive decline is associated with reduced dopaminergic signaling and disrupted theta oscillations, which together impair novelty detection and memory formation. This review shows how VR environments can be used to deliver adaptive, novelty‐rich stimuli that engage dopaminergic circuits and entrain theta rhythms, thereby enhancing ...

Defining a role for the peduncolopontine tegmental nucleus in striatal outflow

, 2012
The pedunculopontine tegmental nucleus (PPTg) lies within the pontomesencephalon and contains cholinergic and non-cholinergic neurones. It has extensive afferent and efferent connections throughout the brain.

Roles of histone lysine methylation in neurodevelopment and related disorders

Ibrain, EarlyView.
This graphical abstract centers on the theme of dynamic balance and systematically outlines the role of histone lysine methylation in neurodevelopment and related disorders. The figure first presents two key classes of regulators that control this balance—“writers” and “erasers”—and then indicates how interactions among different epigenetic ...

Opioid-Mediated Astrocyte–Neuron Signaling in the Nucleus Accumbens

Cells, 2019
Major hallmarks of astrocyte physiology are the elevation of intracellular calcium in response to neurotransmitters and the release of neuroactive substances (gliotransmitters) that modulate neuronal activity.

A light and electron microscopic study of NADPH-diaphorase-,calretinin- and parvalbumin-containing neurons in the rat nucleus accumbens

, 1996
The rat nucleus accumbens contains medium-sized, spiny projection neurons and intrinsic, local circuit neurons, or interneurons. Sub-classes of interneurons, revealed by calretinin (CR) or parvalbumin (PV) immunoreactivity or reduced nicotinamide adenine

Brain Imaging Changes Following Deep Brain Stimulation Patients with Parkinson's Disease: A Literature Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's Disease (PD) is a progressive neurodegenerative disorder primarily characterized by motor symptoms such as tremors, rigidity, and bradykinesia. Structural brain changes, including atrophy in the midbrain, basal ganglia, and cortical regions such as the frontal and temporal lobes, are observed in advanced stages.
