The hippocampal formation plays an important role in cognition, spatial navigation, learning, and memory. High resolution magnetic resonance (MR) imaging makes it possible to study in vivo changes in the hippocampus over time and is useful for comparing hippocampal volume and structure in wild type and mutant mice. Such comparisons demand a reliable way to segment the hippocampal formation. We have developed a method for the systematic segmentation of the hippocampal formation using the perfusion-fixed C57BL/6 mouse brain for application in longitudinal and comparative studies. Our aim was to develop a guide for segmenting over 40 structures in an adult mouse brain using 30 μm isotropic resolution images acquired with a 16.4 T MR imaging system and combined using super-resolution reconstruction.

Perinatal stroke is a vascular injury occurring early in life, often resulting in motor deficits (hemiplegic cerebral palsy/HCP). Comorbidities may also include poor neuropsychological outcomes, such as deficits in memory. Previous studies have used resting state functional MRI (fMRI) to demonstrate that functional connectivity (FC) within hippocampal circuits is associated with memory function in typically developing controls (TDC) and in adults after stroke, but this is unexplored in perinatal stroke.

Objectives: To clarify the role of hippocampal glutamate system in regulating HPA axis in mediating the effect of electroacupuncture (EA) at the heart meridian for improving myocardial injury in rats with acute myocardial ischemia (AMI).
Methods: Male SD rats were randomized into sham-operated group, AMI group, EA group, and L-glutamic acid+EA group (=9). Rat models of AMI were established by left descending coronary artery ligation, and EA was applied at the "Shenmen-Tongli" segment; the rats in L-glutamic acid+EA group were subjected to microinjection of L-glutamic acid into the bilateral hippocampus prior to AMI modeling and EA treatment.

Objectives: To exple the mechanism of Granules (QXZG) for enhancing synaptic plasticity in aging rats.
Methods: Forty SD rats were randomized into control group, aging model group, donepezil treatment group, and QXZG treatment group (=10). Except for the control rats, all the rats were subjected to daily intraperitoneal injection of D-galactose for 8 consecutive weeks to induce brain aging, and donepezil hydrochloride and QXZG suspension were administered by gavage during modeling.

ObjectivesThe objective of this study was to evaluate the occurrence of voltage-gated potassium channel (VGKC) antibodies and the pattern of MRI changes in cats with complex partial seizures with orofacial involvement (CPSOFI), as well as to investigate whether there are factors influencing survival that could be used as prognostic markers in those cats.MethodsCats with CPSOFI were identified retrospectively. The following data were retrieved from the hospital database: signalment, age at first seizure and presentation, the presence of antibodies against VGKC (leucine-rich glioma inactivating factor 1 (LGI1), contactin-associated protein 2 (CASPR2)) and cerebrospinal fluid (CSF) analysis findings.
