We report a patient with paroxysmal aphasia evoked by ictal epileptiform discharges localized to the left fusiform gyrus, where a small brain tumor existed. The intracranial EEG recordings during other seizures demonstrated a close functional link between the left fusiform gyrus and Wernicke's area. The patient also showed transient aphasia with electrical stimulation of the left fusiform gyrus.

Background: The potential pairwise connections among high-sensitivity C-reactive protein (hs-CRP), striatum-based circuits, and anhedonia in adolescent depression are not clear. This study aimed to explore whether hs-CRP levels in adolescents with depression influence anhedonia via alterations of striatum-based functional connectivity (FC).
Methods: A total of 201 adolescents (92 with depressive episodes with anhedonia (anDE), 58 with DE without anhedonia (non-anDE), and 51 healthy controls (HCs)) underwent resting-state functional magnetic resonance imaging (fMRI) and completed the anhedonia subscale of the Children's Depression Inventory (CDI).

Persistent primitive olfactory arteries (PPOAs) are a rare variant of the anterior cerebral artery (ACA). Cerebral aneurysms may arise in the PPOA; most are saccular and on the unilateral PPOA. We report a 66-year-old male with bilateral PPOAs and a fusiform aneurysm on the left side detected at a health check-up.

Although gesture observation tasks are believed to invariably activate the action-observation network (AON), we investigated whether the activation of different cognitive mechanisms when processing identical stimuli with different explicit instructions modulates AON activations. Accordingly, 24 healthy right-handed individuals observed gestures and they processed both the actor's moved hand (hand laterality judgment task, HT) and the meaning of the actor's gesture (meaning task, MT). The main brain-level result was that the HT (vs MT) differentially activated the left and right precuneus, the left inferior parietal lobe, the left and right superior parietal lobe, the middle frontal gyri bilaterally and the left precentral gyrus.

Patients with Moyamoya disease (MMD) exhibit significant alterations in brain structure and function, but knowledge regarding gray matter networks is limited. The study enrolled 136 MMD patients and 99 healthy controls (HCs). Clinical characteristics and gray matter network topology were analyzed.

Background: There are currently no deep learning models applying resting-state functional magnetic resonance imaging (rs-fMRI) data to distinguish patients with Parkinson's disease (PD) and healthy controls (HCs). Moreover, no study has correlated objective gait parameters with brain network alterations in patients with PD. We propose BrainNetCNN + CL, applying a convolutional neural network (CNN) and joint contrastive learning (CL) method to brain network analysis to classify patients with PD and HCs, and compare their performance with classical classification methods.
