Our brain’s post-stroke recovery journey
The damaged brain begins its recovery journey in minutes after stroke. Experts group this into five phases. Find out.
How stroke causes speech problems
Stroke can cause unique speech problems; two common ones include Broca’s aphasia and Wernike’s aphasia. This post explores those two and how stroke creates them. Let us begin with Broca’s aphasia. Broca’s aphasia This type of speech problem occurs due to a stroke attack in Broca’s area. Where is it located? Broca’s area (Figure 1) The Broca’s area rests on the lower part of the left Frontal lobe. I invite you to re-visit the Journeys to the brain: 2 – A walk over the brain surface which introduces different brain lobes. For easy reference, I have included a graphic that appeared in…
The neuron forest
“Neuron” by NIH-NCATS is licensed under CC BY 2.0 Our brain contains about 100 billion neurons; it looks like a neuron forest. because a neuron is more or less similar to a tree. Neurons are a special kind of cell. At one end, it sprouts a large number of very thin short threads – “dendrites”. The ends of these receive electrical signals from other neurons via small fluid-filled ponds – “synapses”. The received signals pass along until it reaches the tree (cell) body. From there, it shoots away to the next neuron through another thicker branch; it is named “Axon”. So, dendrites take electrical…
Understand different stroke types
A stroke can occur either due to a block in an artery or bleeding from an artery. Find out more about it.
Homunculus on our brain surface
“Homunculus” refers to a small human or a “humanoid” creature. Do we have it on our brain surface? Yes, we can find a homunculus (figuratively) as a map in our brain. Not just one, in fact, we have “two little humanoids”!. This is the story behind this amazing discovery. In 1937, two brilliant scientists, Dr Wilder Penfield and Edwin Boldrey embarked on a journey to unravel the mysteries of the human brain. They were operating at McGill University, in Montreal, Canada with a mission to map the brain regions that receive sensory information from the skin and those that send…
