Let’s Talk Lobes

Transcript of Neuro Nugget Video:

In humans, the lobes of the brain are divided by a number of bumps and grooves. The folding of the brain, and the resulting bumps and grooves, increases its surface area and enables more cerebral cortex matter to fit inside the skull. Each half of the brain is divided into four areas called Lobes.

1. The Frontal Lobes are located in the front of the brain. They are very large and have many functions. The frontal lobes manage skills known as Executive Functions. These are very important skills we use for things such as solving problems, planning, making decisions and controlling our behaviour. The frontal lobes work like the conductor of an orchestra who keeps all the musicians playing together harmoniously.

The frontal lobes are particularly vulnerable to injury because they are large and are at the front of the brain. An injury to the frontal lobes can lead to a number of changes including:

  • Difficulties with attention and taking in information.
  • Changes in the ability to control behavior.
  • Increased impulsivity.
  • Poor judgment and decision-making.
  • Difficulty planning things and meeting goals.

2. The Temporal Lobes are located on the side of your brain just above your ears. One of their important functions is to help us process and understand sounds such as soeech and musical notes. Other functions include managing our emotions and recognizing faces. Some Effects of an Injury to the Temporal Lobes might include:

  • Difficulty in recognizing faces, things or places.
  • Difficulty understanding or remembering what people say.
  • Difficulty reading.
  • Difficulty recognizing objects.
  • Short-term memory difficulties.
  • Increased aggression.

3. The Parietal Lobes are located behind the frontal lobes and above the temporal lobes. One of their main functions is to allow us to make sense of things we touch – for example, whether an object is smooth or sharp, firm or soft. The parietal lobes also tell us where our body is in relation to the objects around us. This allows us to move around without bumping in to things. This function is known as Visuospatial Processing.

The parietal lobes are also important for skills such as maths, spelling, hand-eye coordination and fine motor movements such as tying shoe laces. Some Effects of an Injury to the Parietal Lobes could be:

  • Difficulty naming objects.
  • Difficulty in distinguishing left from right.
  • Difficulties with hand-eye coordination.
  • Difficulty knowing the function of an object.
  • Problems with reading , writing, or math.
  • Difficulty knowing where things are in relation to our own bodies; for example, how close an object is to us.

4. The Occipital Lobes are located at the back of the brain. They have an important role in vision because they allow us to make sense of information that comes from our eyes. This process is known as Visual Perception. Some effects of an injury to the Occipital lobes would be:

  • Blurred vision or sight loss.
  • Visual hallucinations and distortions.
  • Difficulty with identifying colours
  • Difficulty recognizing words.
  • Difficulty recognizing when people, or things, are moving

…Recognizing what lobe does what helps us gain a better understanding overall of the amazing wonder between our ears known as the human brain.
