Psychedelics Stimulate Hippocampal Cells to Alleviate Anxiety

When I first read “DMT: The Spirit Molecule” by Dr. Rick Strassman, I thought developing psychedelic inspired drugs without any “hallucinating” side-effects to cure anxiety related problems could be a game changer. Interestingly, I came across research by Cornell University, where researchers did come up with psychedelics to excite cells in hippocampus to reduce anxiety.

CAMs: Key Players in Modulating Post-Stroke Immune Responses

When a blood clot blocks an artery, it leads to an ischemic stroke. The blockage or ischemic stroke prevents blood and oxygen from reaching areas of the brain. This gives rise to one of the following symptoms: According to the statistics, the older one gets, the higher the risk of experiencing ischemic strokes. Although, neuroscience has helped us understand what happens in the body during a stroke. However, we have no idea how the immune system helps with recovery after a stroke.

Nanoparticles Break Blood-Brain Barrier for Cancer Treatment: Targeting Metabolic Adaptability

Scientists at the Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine, have crafted a tiny particle capable of crossing the blood-brain barrier. The team envision to tackle both primary breast cancer tumors and brain metastases in a single treatment. Their investigations indicate that this approach can reduce the size of both breast and brain tumors in lab experiments.

Mitochondrial Energy Crisis: Unraveling the Alzheimer’s Puzzle

Brain cells crave immense energy to survive and communicate through connections known as synapses. These cells are like energy enthusiasts, which are busy in making way through synapses. But, in the Alzheimer’s scenario, it’s like they’re facing an energy crisis. This messes up their power production. And so, it leads to crumbling down of the synapses and consequently, our fresh memories slowly slip away.

Lactate Enriches Neurogenesis: Neuronal Differentiation

Scientists at Tohoku University, Sendai, Japan made an exciting discovery regarding cellular mechanisms that assist in developing our brains. They discovered that lactate plays an important role in helping neural stem cells become specialized neurons. Lactate happens to be the by-product of exercise and metabolism. Researchers even gave this process a fancy name: neuronal differentiation.

Omega-3 Slow ALS Progression: Fatty Acid has Neuroprotective Effects

Recent study led by Harvard T.H. Chan School of Public Health suggests that a diet high in alpha-linolenic acid (ALA) may have potential benefits for individuals with amyotrophic lateral sclerosis (ALS). ALS is a progressive neurodegenerative disease that affects nerve cells responsible for controlling muscle movement.

Targeting Folate Receptors in Gliomas: A New Way to Detect Brain Tumors

Recent research conducted by Maxwell Miner from the University of Turku in Finland, working at the Turku PET Centre, sheds light on the potential of folate receptors as a valuable tool in the field of brain tumor imaging and treatment. Folate-based radiopharmaceuticals are a type of medical imaging agent that combines folate – a form of vitamin B9 – with a radioactive substance.

Distinct Activation Patterns of Projection Neurons: Cortical Dynamics

Cerebral cortex is the outer layer of cerebrum, that is the largest part of the brain. All kinds of higher-level processes such as language, memory, and decision-making are performed in this region. The complex, densely packed structure is saturated with various types of neurons. It is extremely difficult to image its neuronal dynamics with the necessary spatial and temporal resolution. So far, fMRI (functional magnetic resonance imaging) technique is widely used for studying brain activity. However, when it comes down to examine neural circuitry at the point of a single…

Astrocytes are the Information Regulators: Brain Pathology

Astrocytes are the non-neuronal cells that provide support and maintenance to neurons in the brain and spinal cord. They have a star-shaped morphology, with multiple branching processes that extend out from the cell body. They form specialized junctions with blood vessels for regulating the transport of nutrients and other molecules between the brain and the bloodstream.

Neuro-Stack to records Single Neuron Activity: Brain Mechanisms of Movement

New technologies have revolutionized many fields, including medicine and neuroscience. Advances in engineering, materials science, and computer technology have enabled the development of increasingly sophisticated devices for recording and analysing biological signals, such as brain activity, with unprecedented precision and accuracy. For instance, electroencephalography (EEG) is a non-invasive technique that measures electrical activity in the brain using electrodes placed on the scalp. With the advancement in electronics and computing the EEG signals can now be recorded with greater precision and resolution.

Hydrogels Promote Neuronal Tissue Growth: Brain Healing

Degeneration of brain cells could be a natural aging process. However, destruction or deterioration of brain cells could occur due to a wide range of internal as well as external factors. In general, brain damage refers to significant, undiscriminating trauma-induced damage. Science has tremendously advanced when it comes to health care and disease control. There are new and radical developments in the field of neurology alone. One such progress is brain tissue reconstruction.

Book Review: The Brain by Dr. David Eagleman

Dr. David Eagleman is a neuroscientist at Stanford, NYT bestselling author, Writer/Host of THE BRAIN on PBS, and the list continues. After listening to his podcasts and TED talks, I decided to pick-up one book from his vault – The Brain: The Story of You. The book is an interesting read and at some points, quite an eye opener. Here, Dr. Eagleman reviews how the human brain develops and make sense of the data that it receives from sensory systems. We are built to perceive only thin slice of perception,…
