Primates possess a sophisticated cognitive ability to interpret and respond to the social actions of conspecifics. Neurons in the temporal lobes of macaque monkeys which are selective for the appearance and motions of conspecifics have been described previously; the results reported here indicate that pathways which integrate such information converge in mesial temporal regions. Single neuron data from an alert macaque viewing moving pictures of other monkeys engaged in a variety of behaviors are presented. Neurons in medial nuclei of the amygdala and adjacent mesial temporal cortex are sensitive to identity, movement, and high-level aspects of depicted scenes.

Purpose: In resective epilepsy surgery for drug-resistant focal epilepsy (DRE), good seizure outcome is strongly associated with visualization of an epileptogenic lesion on MRI. Standard clinical MRI (≤ 3 Tesla (T)) may fail to detect subtle lesions. 7T MRI enhances detection and delineation, the potential benefits of increasing field strength to 9.

Objective: To examine neuropsychological characteristic differences between typical and atypical language dominance in adult persons with epilepsy (PWE) and mesial temporal sclerosis (MTS), including exploring the impact of selected clinical variables on detection of atypical language and neuropsychological performance.
Methods: Adults with intractable epilepsy and MTS ( = 39) underwent comprehensive, pre-surgical evaluation including fMRI and neuropsychological assessment. Participants with concordant lateralization of MTS and seizure onset were included.

Background And Purpose: Epilepsy, a globally prevalent neurological disorder, necessitates precise identification of the epileptogenic zone (EZ) for effective surgical management. While the individual utilities of FDG PET and FMZ PET have been demonstrated, their combined efficacy in localizing the epileptogenic zone remains underexplored. We aim to improve the non-invasive prediction of epileptogenic zone (EZ) in temporal lobe epilepsy (TLE) by combining FDG PET and FMZ PET with statistical feature extraction and machine learning.

Objective: to study the anatomical feasibility of laser fiber insertion for interstitial thermal therapy via transorbital approach to the temporo-mesial structures (amygdala-hippocampus-parahippocampus complex).
Methods: Anatomical dissections were performed bilaterally on two human cadaveric heads via a transorbital approach, in which screws and laser fibers were used for magnetic resonance imaging-guided laser interstitial thermal therapy (MRIgLITT) assisted by neuronavigation. In addition, eight transorbital trajectories were simulated using the transorbital entry points obtained from a cadaveric radiological study of four patients previously operated on for mesial temporal lobe epilepsy.

Bilingual language control is a dynamic cognitive system that enables individuals to effectively manage language use and prevent interference when switching between languages. Research indicates that certain neurodegenerative conditions may influence language-switching abilities or hinder the suppression of cross-language interference. However, it remains uncertain whether neurodegeneration primarily affecting mesial temporal structures, such as Mild Cognitive Impairment (MCI), impacts lexical retrieval in dual-language naming conditions.
