We report on a 19-year-old patient with a 4-year history of lying and cheating who presented neuropsychological abnormalities regarding attention deficits, hyperactivity and impulsivity. Cerebral magnetic resonance imaging scans revealed schizencephaly of the right central region, dysgenesia of the corpus callosum, a noneverted gyrus cinguli and hypoplasia of the left cerebellar hemisphere. Although the patient did not fulfill the diagnostic criteria for attention-deficit/hyperactivity disorder, we suggest that the patient's behavioral alteration could be related to the neuroanatomical alterations, especially the aplasia of the gyrus cinguli.

The purpose was to explore the spatial centrality of the whole brain functional network related to migraine and to investigate the potential functional hubs associated with migraine. 32 migraine patients and 55 healthy controls were recruited and they received resting-state functional magnetic resonance imaging voluntarily. Voxel-wise Degree Centrality (DC) was measured across the whole brain, and group differences in DC were compared.

Transcutaneous vagus nerve stimulation (tVNS) offers a non-invasive method to enhance noradrenergic neurotransmission in the human brain, thereby increasing cognitive control. Here, we investigate if changes in cognitive control induced by tVNS are mediated through locus coeruleus-induced modifications of neural activity in the anterior cingulate cortex. Young healthy participants engaged in a simple cognitive control task focusing on response inhibition and a more complex task that involved both response inhibition and working memory, inside a magnetic resonance imaging scanner.

Fibromyalgia is a chronic pain condition contributing to significant disability worldwide. Neuroimaging studies identify abnormal effective connectivity between cortical areas responsible for descending pain modulation (pregenual anterior cingulate cortex, pgACC) and sensory components of pain experience (primary somatosensory cortex, S1). Neurofeedback, a brain-computer interface technique, can normalise dysfunctional brain activity, thereby improving pain and function.

Cuprizone (CPZ) is a widely used toxin that induces demyelinating diseases in animal models, producing multiple sclerosis (MS)-like pathology in rodents. CPZ is one of the few toxins that triggers demyelination and subsequent remyelination following the cessation of its application. This study examines the functional consequences of CPZ-induced demyelination and the subsequent recovery of neural communication within the anterior cingulate cortex (ACC), with a particular focus on interhemispheric connectivity via the corpus callosum (CC).

Background: The clinical characteristics of major depressive disorder (MDD) in adolescents show notable gender-related differences, but the cause of these differences is still not understood. The current research concentrates on the changes in neurometabolism and neuroendocrine function, aiming to identify differences in endocrine function and brain metabolism between male and female adolescents with MDD.
Methods: A total of 121 teenagers diagnosed with MDD (43 males and 78 females) were enlisted as participants.
