Neuro 🧠

1) Compress brain tissue, as the growing mass presses against nearby brain structures, interfering with their function - can led to loss of functions in areas, e.g. motor movement

2) Increased Intracranial Pressure - tumor growth raises pressure inside it, as the skull is fixed space. Symptoms include - persistent headaches, nausea, and vomiting etc.

3) Disruption of electrical activity

Irritation at surrounding brain tissues would trigger abnormal electrical signals, leading to seizures

4: Region-specific dysfunction

Frontal lobe - personality changes, impaired judgement

Hi everyone, and welcome back! Apologies for the short break over the past 2 weeks - I hope everyone's working hard for their year 12 mocks! Today, we're gong to be exploring the cerebellum.

In GCSE biology, we've learn that the cerebellum controls movement and motor activity.

But do you know that it is also the second largest part of the brain?

The cerebellum stands for 'little brain',and it covers 11% of the brain mass. It is located at the back of the brain and consists of two hemispheres which are connected by the vermis (the midline portion of the cerebellum).

There are three lobes in the cerebullum, the anterior lobe, the posterior lobe and the flocculonoular lobe and these lobes are divided by the pirmary fissure and posterolateral fissure. There are also three cerebellar zones as seen from the picture below:

Today, we're exploring the principal regions of the brain, starting with the cerebrum.

The cerebrum is the largest part of the brain. It consists of two cerebral hemispheres and is organised into an outer cerebral cortex and inner areas of grey and white matter. Deep within the cortex lie the basal ganglia, which play a key role in motor control.

The cerebrum is divided into right and left hemispheres, which are connected by a bundle of white matter called the corpus callosum.

The right hemisphere is associated with creativity, imagination, and visual imagery.

The left hemisphere is linked to problem-solving, reasoning, and language processing.

Hi guys, for everyone who's curious about the brain, I've decided to introduce a season on brain anatomy!!

In each post, we will dive into a specific part of the brain, breaking it down into bite-sized, easy-to-digest info. The goal is to keep it simple and quick - so we can all learn something new about the brain!

Today's post starts with a super basic intro to brain anatomy- let's get into it!

VISUALISING AND NAVIGATING THE BRAIN

• the brain is a 3D structure, but we can also visualise it in a 2D structure
