Abstract:
Background: Understanding Alzheimer’s disease (AD) in terms of its various pathophysiological pathways is essential to unravel the complex nature of the disease process and identify potential therapeutic targets. The renin-angiotensin system (RAS) has been implicated in several brain diseases, including traumatic brain injury, ischemic stroke, and AD. Objective: This study was designed to evaluate the protein expression levels of RAS components in postmortem cortical and hippocampal brain samples obtained from AD versus non-AD individuals. Methods: We analyzed RAS components in the cortex and

Abstract In addition to surgical resection and systemic therapy, whole brain radiotherapy (WBRT) is a crucial modality in the treatment of cancers that have metastasized to the brain. It has been shown to improve intracranial disease control and overall survival. However, WBRT also increases the risk of radiation-associated damage to sensitive structures like the hippocampus, often resulting in neurocognitive dysfunction and decline. Hippocampal avoidance WBRT (HAWBRT) has been shown to reduce neurocognitive sequalae without worsening survival outcomes or increasing the risk of metastasis to t

The hippocampus is a critical brain substrate for learning and memory; events that harm the hippocampus can seriously impair mental and behavioral functioning. Hippocampal pathophysiologies have been identified as potential causes and effects of a remarkably diverse array of medical diseases, psychological disorders, and environmental sources of damage. It may be that the hippocampus is more vulnerable than other brain areas to insults that are related to these conditions.

A prolonged and substantial depression of the CA1 population spike was produced by a brief but intense noxious stimulus applied to the tail. This depression was temperature-dependent and habituated to subsequent noxious stimuli applied more than 1 hr later. I

High frequency repetitive stimulation of an excitatory input in the hippocampus results in a post-tetanic potentiation (PTP) of short duration (about 3 min) that can be followed by a long-term synaptic potentiation (LTP) of the same excitatory input (Schwartzkroin and Wester, 1975; Andersen et al., 1977). It has been reported that this tetanus-induced LTP cannot be elicited in a Ca²⁺-free medium and is therefore a Ca²⁺-dependent process (Dunwiddie et al., 1978; Dunwiddie and Lynch, 1979; Wigstrӧm et al., 1979).

Abstract:
Changes in mechanical properties within brain tissues after losses in cell viability have not been well investigated. Lack of oxygen and nutrient transport can induce hypoxic neuronal injury and increase cell membrane permeability, and cell membranes and matrix components can lose their structural and mechanical integrity. These physical changes may have an effect on mechanical properties of brain tissue [1]. In this study, the viscoelastic behavior of two anatomical regions (cerebral cortex and hippocampus) in acute rat brain tissue slices were measured as a function of cell viability using i

Abstract:
Epilepsy affects an estimated one out of 150 people, with 30% of patients unresponsive to existing drug- based therapies for seizure management. Hippocampal resection can be a curative procedure for drug-resistant temporal lobe epilepsy [1], however, current rates of surgical resection are limited by perceived and real risks of undergoing neurosurgery [2]. Laser Interstitial Thermal Therapy (LITT) is a less invasive alternative to surgical resection, which heats brain tissue causing thermal necrosis [3]. Existing commercial LITT tools (Medtronic, Monteris) are straight probes which are inserte

Abstract:
Is the perineuronal net structure within emotional processing brain regions associated with changes in affective state? The objective of this scoping review is to bring together the literature on human and animal studies which have measured perineuronal net structure in brain regions associated with emotional processing (such as but not limited to amygdala, hippocampus and prefrontal cortex). Perineuronal nets are a specialised form of condensed extracellular matrix that enwrap and protect neurons (Suttkus et al., 2016), regulate synaptic plasticity (Celio and Blumcke, 1994) and ion homeostasi
