Deer show a gender difference in the neural regulation of appetite by the brain
Brain chemicals , called neuropeptides , regulate seasonal changes in reproductive function and appetite. We took brains from red deer males and females at two contrasting seasons of the year and examined specific regions of the hypothalamus
Failure to launch: Boredom in the brain
We’ve all been bored at one time or another. Nothing like the popular notion of the “couch potato”, we define boredom as an inability to engage with one’s environment despite the motivation to do so – a
Neurocysticercosis
Neurocysticercosis is an infection of the nervous system and commonly resulted by the ingestion of Taenia solium eggs (pork tapeworm) after consuming undercooked pork, or contaminated water. The parasite can grow in the brain and spinal cord
Neuroprotection for stroke: Progesterone treatment reduces brain mitochondrial dysfunction
Every year, six million people die from stroke and five million are left disabled. 80% of strokes are ischemic and happen when blood flow is blocked in a part of the brain, due to occlusion of brain
Upregulation of a protein in the brains of patients with neurodegenerative diseases due to its altered membrane binding
The proteins of the Neuronal Calcium Sensor (NCS) family act as calcium dependent molecular switches in order to maintain the communication between the brain cells. Most of NCS proteins are involved in neurodegenerative diseases resulting from calcium
Water on the brain? Putting the “Hydro” on the “Cephalus”
Hydrocephalus, in the most basic sense, means an increased amount of fluid in the spaces of the brain. This fluid is specifically called cerebrospinal fluid (CSF) with “cerebro” referring to brain and “spinal” referring to the spinal
Deaf people are more likely to be left-handed – unless they are also signers
The hand that we prefer to use – the right or the left one – speaks about how our brain is organized. For example, if we are strongly right-handed (i.e., we prefer the right hand for almost
The new subregion in parahippocampal region founded integrated the two memory-related brain networks
The parahippocampal region (PHR) is an interface region between the hippocampus and the neocortex located in the medial temporal lobe (MTL). The PHR has been implicated in many functions, including long-term memory, working memory, and perception. Given
Vitamin D and T cells in multiple sclerosis: how to measure an effect?
Multiple sclerosis (MS) is an inflammatory disease of the brain, leading to disability in patients suffering from this disease. A type of white blood cells, T cells, are important pathogenic cells which drive this inflammation in early
Vitamin E helps protect healthy fats critical for brain development
During development, the brain requires more oxygen than any other organ – about 60% of the total oxygen consumed by a growing fetus is used to support the high metabolic demands of neurodevelopment. This means the developing
How can lithium prevent stroke – Is the inner cell layer of our vessels the key?
Since decades, lithium is one of the most effective drugs for psychiatric diseases such as bipolar disorders; but lithium has a narrow therapeutic window. This means that lithium concentration in patients’ blood should be kept in a
Music as a medicine for sudden hearing loss
Sudden sensorineural hearing loss (SSHL) is a disease that suddenly affects hearing in one ear without any special trigger and is often accompanied by tinnitus (a ringing in the ear), ear fullness, vertigo, dizziness. The rate of
The olfactory system may extract sensory information by summating signals from multiple receptors
We interpret the world around us by means of individual sensory nervous systems, vision, hearing, touch, taste, smell, and balance/movement. These systems transduce the physical world into neural information in the brain through multi-step processes. Generally, one
The effects of brain stimulation on cognitive inhibition
The term cognitive inhibition refers to the ability to control or suppress irrelevant responses, and to adopt instead relevant and flexible responses. A common situation that requires cognitive inhibition includes for example, the resistant to check messages
Energy intensive hub regions of the brain
In this work, we analyzed a massive database of brain connectivity data from the Allen Mouse Brain Connectivity Atlas, which contains data from experiments where researchers inject viral tracers into different regions of the mouse brain. The
Comparison of the effect of exercise on late-phase LTP of the dentate gyrus and CA1 of Alzheimer’s disease model
There has been a recent upsurge of scientific reports about the benefits of regular physical exercise for general health and particularly for mental health. Healthy diet and physical activity have emerged as promising low-cost measures for protection
Consuming a probiotic once a day could improve cognitive skills
Probiotics, which are friendly and beneficial bacteria to our bodies, could improve cognitive skills, i.e the ability to learn, memorise, process information or react to events, as demonstrated by researchers at the APC Microbiome Institute, University College
Emergency department presentation predicts poor outcomes after meningioma removal
A meningioma is one of the most common forms of a brain tumor. Unlike many other types of brain tumors, meningiomas are typically associated with relatively favorable outcomes even when they require surgical treatment. In the past
Do plants have brains?
Many organisms have circadian clocks. These internal clocks play essential roles for predicting day-length or seasons, and they regulate behavior and hormonal secretion in animals, and also regulating flowering time and cell elongation in plants. In animals,
Food and Nutrition cause liver and brain diseases with diabetes in the developing and developed world
In the world the consumption of a healthy diet is essential to prevent diseases such as obesity, diabetes and brain diseases. New discoveries in medicine indicate that a diet that is low in fat and carbohydrate lower
