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.

Reduced γ-Aminobutyric Acid and Glutamate+Glutamine Levels in Drug-Naïve Patients with First-Episode Schizophrenia but Not in Those at Ultrahigh Risk

open access: yesNeural Plasticity, 2016
Altered γ-aminobutyric acid (GABA), glutamate (Glu) levels, and an imbalance between GABAergic and glutamatergic neurotransmissions have been involved in the pathophysiology of schizophrenia. However, it remains unclear how these abnormalities impact the

Psychotic disorders induced by antiepileptic drugs in people with epilepsy.

open access: yesBrain : a journal of neurology, 2016
Antiepileptic drug treatment can induce psychosis in some patients. However, there are no agreed definitions or diagnostic criteria for antiepileptic drug-induced psychotic disorder in the classification systems of either epileptology or psychiatry.

The Dynamics of Triple Interactions in Resting fMRI: Insights into Psychotic Disorders [PDF]

open access: yesarXiv
The human brain dynamically integrated and configured information to adapt to the environment. To capture these changes over time, dynamic second-order functional connectivity was typically used to capture transient brain patterns. However, dynamic second-order functional connectivity typically ignored interactions beyond pairwise relationships.

A Survey of Large Language Models in Mental Health Disorder Detection on Social Media [PDF]

open access: yesarXiv
The detection and intervention of mental health issues represent a critical global research focus, and social media data has been recognized as an important resource for mental health research. However, how to utilize Large Language Models (LLMs) for mental health problem detection on social media poses significant challenges. Hence, this paper aims to

A computational account of the development and evolution of psychotic symptoms [PDF]

open access: yes
The mechanisms of psychotic symptoms like hallucinations and delusions are often investigated in fully-formed illness, well after symptoms emerge. These investigations have yielded key insights, but are not well-positioned to reveal the dynamic forces underlying symptom formation itself.
