Pediatric applications of transcranial magnetic stimulation are rapidly expanding, but lack the safety data established for adults. Transcranial magnetic stimulation-induced neurocardiogenic syncope may represent an age-dependent adverse event that is essentially undescribed in the transcranial magnetic stimulation literature. We report on 2 adolescents (of 10 children studied) with transcranial magnetic stimulation-related neurocardiogenic syncope, identify modifiable risk factors, and suggest measures to improve the safety of future pediatric transcranial magnetic stimulation studies.

Adult neurogenesis has most often been studied in the hippocampus and subventricular zone-olfactory bulb, where newborn neurons contribute to a variety of behaviors. A handful of studies have also investigated adult neurogenesis in other brain regions, but relatively little is known about the properties of neurons added to non-canonical areas. One such region is the striatum.

Purpose Of Review: This paper aims to review pudendal neuralgia pathophysiology, risk factors, diagnosis, and treatment options.
Recent Findings: Conservative and pharmacologic options are first line treatments for the treatment of pudendal neuralgia. Interventional treatment such as, pudendal nerve blocks can be tried if first line treatments feel to provide adequate analgesia.
Involvement of aSPOC in the online updating of reach-to-grasp to mechanical perturbations of hand transport.

Humans adjust their movement to changing environments effortlessly via multisensory integration of the effector's state, motor commands, and sensory feedback. It is postulated that frontoparietal (FP) networks are involved in the control of prehension, with dorsomedial (DM) and dorsolateral (DL) regions processing the reach and the grasp, respectively. This study tested (5F, 5M participants) the differential involvement of FP nodes (ventral premotor cortex - PMv, dorsal premotor cortex - PMd, anterior intraparietal sulcus - aIPS, and anterior superior parietal-occipital cortex - aSPOC) in online adjustments of reach-to-grasp coordination to mechanical perturbations that disrupted arm transport.

How the prefrontal cortex contributes to working memory remains controversial, as theories differ in their emphasis on its role in storing memories versus controlling their content. To adjudicate between these competing ideas, we tested how perturbations to the human (both sexes) lateral prefrontal cortex impact the storage and control aspects of working memory during a task that requires human subjects to allocate resources to memory items based on their behavioral priority. Our computational model made a strong prediction that disruption of this control process would counterintuitively improve memory for low-priority items.

Repetitive transcranial magnetic stimulation (rTMS) is acknowledged for its critical role in modulating neuronal excitability and enhancing cognitive function. The dentate gyrus of the hippocampus is closely linked to cognitive processes; however, the precise mechanisms by which changes in its excitability influence cognition are not yet fully understood. This study aimed to elucidate the effects on granule cell excitability and the effects on cognition of high-frequency rTMS in naturally aging mice, as well as to investigate the potential interactions between these two factors.
