Article Synopsis
- The cerebral cortex has organized areas that are connected by axons, but how neurogenesis (the development of new neurons) is coordinated between these areas isn’t well understood.
- The somatosensory cortex is important for processing touch and receives sensory information through the thalamus to its primary and secondary areas.
- Our study found that neuron production in the secondary somatosensory cortex (S2) happens before the primary somatosensory cortex (S1) and ends sooner, with a decrease in upper-layer neurons in S2 due to a change at the surface layer, suggesting a specific mechanism that organizes the development of these cortical areas.
A 58-year-old man was treated with radical excision for rectal cancer. Pathological findings were pT3N1M0, Stage ⅢB, RAS: mutant, BRAF: mutant, MSS. The patient was followed up without adjuvant chemotherapy.

Amplicon sequencing of amoA is a widely used method; however, it produces inaccurate results owing to the lack of a 'universal' primer set. Moreover, currently available primer sets suffer from amplification biases, which can lead to severe misinterpretation.

Blood tests revealed elevated C-reactive protein and myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA). Contrast-enhanced magnetic resonance imaging of the head showed hypertrophic pachymeningitis of the left middle cranial fossa with compression of the cranial nerves, including the trigeminal (V), facial (VII), glossopharyngeal (IX), and vagal (X) nerves, resulting in cranial nerve palsy.

Methods And Results: We retrospectively registered patients clinically diagnosed with myocarditis after the first or second mCV who underwent endomyocardial biopsy or autopsy from 42 participating centers in Japan. We investigated the histological features and their association with clinical presentation based on cardiomyocyte injury.
