Article Abstract
To enable an accurate recognition of neuronal excitability in an epileptic brain for modeling or localization of epileptic zone, here the brain response to single-pulse electrical stimulation (SPES) has been decomposed into its constituent components using adaptive singular spectrum analysis (SSA). Given the response at neuronal level, these components are expected to be the inhibitory and excitatory components. The prime objective is to thoroughly investigate the nature of delayed responses (elicited between 100[Formula: see text]ms-1 s after SPES) for localization of the epileptic zone. SSA is a powerful subspace signal analysis method for separation of single channel signals into their constituent uncorrelated components. The consistency in the results for both early and delayed brain responses verifies the usability of the approach.

Autism spectrum disorders (ASD), a group of neurodevelopmental disorders characterized by the core symptoms of impaired social communication and stereotyped behaviors, is strongly associated with dysregulated microbiota-gut-brain axis. Emerging evidence suggests that , which showed reduced abundance in ASD cohorts, holds therapeutic potential, though its interaction with host remain unexplored. Here, we investigated the efficacy and molecular basis of 4P-15 (4P-15) in BTBR /J (BTBR) mice, an idiopathic ASD mouse model.

Background: Despite advances in understanding the effective connectivity (EC) of brain networks in leucine-rich glioma-inactivated 1 (LGI1) antibody encephalitis, the specific cause and underlying mechanisms of LGI1 encephalitis remain unclear.
Materials And Methods: The study included 27 patients with anti-LGI1 encephalitis and 28 age- and sex-matched normal controls. Amplitude of low-frequency fluctuation (ALFF) analysis identified altered brain regions.

Background: Theta Burst Stimulation (TBS) is a form of non-invasive brain stimulation that can induce neuroplastic changes in the underlying intracortical areas. It has significant potential in clinical and research settings for modulating cognitive and motor performance. Little is known about how TBS affects oxygenations levels within and across brain hemispheres during stimulation of the Dorsolateral Prefrontal Cortex (DLPFC).

Glutamate is an important neurotransmitter in the mammalian brain. Among the receptors that glutamate interacts with is metabotropic glutamate (mGlu) receptor 2, a Gα-coupled receptor. These receptors are primarily located on glutamatergic nerve terminals and act as presynaptic autoreceptors to produce feedback inhibition of glutamate release.

Objectives: To investigate the therapeutic effect of acupuncture in a rat model of insomnia and its regulatory effect on the glutamic acid (Glu)/γ-aminobutyric acid (GABA)-glutamine (Gln) metabolic loop.
Methods: Forty male SD rats were randomly assigned to control group, model group, group and group (=10). In the latter 3 groups, rat models of insomnia were established by intraperitoneal injections of p-chlorophenylalanine and verified using a sodium pentobarbital-induced sleep test.
