BACKGROUND Adult neurogenesis occurs in the hippocampus of most mammals, including humans, and plays an important role in hippocampal-dependent learning. This process is highly regulated by neuronal activity and might therefore be vulnerable to anesthesia. In this article, the authors investigated this possibility by evaluating the impact of propofol anesthesia on mouse hippocampal neurons gene...
Objective The hippocampal circuit integrity is crucial for learning and memory. Despite the existing reports on hippocampal–dependent memory impairment due to noise stress, there are only a few studies on the effect of noise stress on anatomical structure of hippocampus. The present study is aimed to investigate the likely effects of chronic noise exposure on the volume of rat hippocampus. Mate...
Polymorphisms in the Synapsin III (Syn III) gene can associate with attention deficits and hyperactivity disorder (ADHD), a neurodevelopmental characterized by alterations mesocorticolimbic nigrostriatal dopaminergic pathways. In spite of evidence supporting that Syn controls development cortical hippocampal short-projecting neurons, whether it plays similar role midbrain neurons (mDN), owning ...
Genetic variations in CACNA1C, which encodes the Cav1.2 subunit of L-type calcium channels (LTCCs), are associated with multiple forms of neuropsychiatric disease that manifest high anxiety in patients. In parallel, mice harboring forebrain-specific conditional knockout of cacna1c (forebrain-Cav1.2 cKO) display unusually high anxiety-like behavior. LTCCs in general, including the Cav1.3 subunit...
Alzheimer’s disease (AD) is undoubtedly one of the serious and growing public health challenges in the world today. There is an unmet need for new and effective preventative and therapeutic treatment approaches for AD, particularly at early stages of the disease. However, the underlying mechanism against Aβ-induced electrophysiological alteration in cultured hippocampal pyramidal neurons is st...
The hippocampus is involved in episodic memory, which is composed of subjective experiences in the multisensory world; however, little is known about the subthreshold membrane potential responses of individual hippocampal neurons to sensory stimuli. Using in-vivo whole-cell patch-clamp recordings from hippocampal CA1 neurons in awake mice, we found that almost all hippocampal neurons exhibited ...
The distributions of isoforms of the Na,K-ATPase alpha subunit were determined in mature cultured hippocampal neurons and in a polarized epithelial cell line. We find that hippocampal neurons express the alpha 1 and alpha 3 isoforms in the membranes of both axons and dendrites. In contrast the alpha 1 and alpha 3 proteins are exclusively basolateral when expressed endogenously or by stable tran...
Amentoflavone is a natural biflavone compound with many biological properties, including anti-inflammatory, antioxidative, and neuroprotective effects. We presumed that amentoflavone exerts a neuroprotective effect in epilepsy models. Prior to model establishment, mice were intragastrically administered 25 mg/kg amentoflavone for 3 consecutive days. Amentoflavone effectively prevented pilocarpi...
The hippocampus is one of the brain regions involved in cognitive functions, including learning and memory. Extensive studies have unveiled how information is processed within this system. However, the mechanisms by which hippocampal activity is translated into action remain unsolved. One important target of hippocampal projections is the nucleus accumbens, which has been described as the motiv...
Dissociated hippocampal neuron culture has long been the model system of choice for many neuroscientists. The ability to culture dissociated hippocampal neurons from genetically modified mice provides an invaluable tool for studying many neuronal processes. In this study, we established a novel method to culture dissociated hippocampal neurons from embryonic and neonatal mice. Dissociated neuro...
