What is the reptile brain?

Why do they call it the reptilian brain?

The phrase “reptilian brain” derives from the fact that a reptile’s brain is dominated by the brainstem and cerebellum, which control instinctual thinking and behavior for survival.

What is the reptilian part of the brain?

In MacLean’s triune brain model, the basal ganglia are referred to as the reptilian or primal brain, as this structure is in control of our innate and automatic self-preserving behavior patterns, which ensure our survival and that of our species.

What is the function of the reptilian brain?

The reptilian brain, the oldest of the three, controls the body’s vital functions such as heart rate, breathing, body temperature and balance. Our reptilian brain includes the main structures found in a reptile’s brain: the brainstem and the cerebellum.

How does reptilian brain affect human behavior?

The Reptilian Triune Brain is the oldest relative portion of the Human Brain and drives the instinctive needs to survive, such as eating, procreate with other Humans during sexual intercourse or otherwise the continuation of its own self-procreation.

How do I control my reptilian brain?

Then use all the weapons at your disposal to combat resistance:

  1. Do not judge yourself. …

  5. Act first, think later. …
  6. Do not be afraid to fail. …
  7. If all else fails, remember how the idea was born.


Is reptilian brain the same as brain stem?

The brainstem is the oldest part of the brain as it’s the first to develop. That’s why we call it the “reptilian brain”. Well, this oldie is responsible for all the vital respiratory and cardiac functions. It also acts as the information vehicle to the spinal cord.

What is reptilian behavior?

MacLean proposed that the reptilian complex was responsible for species-typical instinctual behaviours involved in aggression, dominance, territoriality, and ritual displays. Paleomammalian complex. This consists of the septum, amygdalae, hypothalamus, hippocampal complex, and cingulate cortex.

What is the crocodile brain?

To make a long story short, human brains seem to have developed in three stages. The First stage, believe it or not, is what science calls “the crocodile brain,” AKA the “croc brain.” It is the most primitive part of our cognitive process and it is the first gatekeeper that any new information must pass.

What is lizard brain mentality?

Many people call it the “Lizard Brain,” because the limbic system is about all a lizard has for brain function. It is in charge of fight, flight, feeding, fear, freezing up, and fornication. The limbic system is much more powerful than we humans credit it to be.

How old is the reptilian brain in humans?

about 400 million years ago

The Reptilian Brain



This is the oldest part of the brain. It developed about 400 million years ago. It consists of the main structures found in a reptile’s brain: the brain stem and cerebellum.

How do you calm a lizard brain?

And by the time that happens. It's really difficult for that brain to say calm down here's the right answer you just have to walk down an airplane when they're picked experiencing turbulence.

What are the cerebellum’s functions?

The cerebellum (which is Latin for “little brain”) is a major structure of the hindbrain that is located near the brainstem. This part of the brain is responsible for coordinating voluntary movements. It is also responsible for a number of functions including motor skills such as balance, coordination, and posture.

What are the symptoms of a damaged cerebellum?

Damage to the cerebellum can lead to: 1) loss of coordination of motor movement (asynergia), 2) the inability to judge distance and when to stop (dysmetria), 3) the inability to perform rapid alternating movements (adiadochokinesia), 4) movement tremors (intention tremor), 5) staggering, wide based walking (ataxic gait …

How do you heal the cerebellum?

The key to healing any brain injury, including cerebellar injuries, is to engage your brain’s neuroplasticity. Completing therapy exercises daily can promote improvements in your balance, coordination, and cognitive skills. You may even experience a full recovery, depending on how severe your injury was.

Can a person with a severely damaged cerebellum speak?

Cerebellar lesions are most often associated with the clinical findings of ataxia, which may affect the limbs, trunk, or even speech (producing a specific type of dysarthria known as scanning speech), dysequilibrium as manifested by a wide-based gait, and muscular hypotonia.

Which symptoms is the client who has a tumor of the cerebellum most likely to exhibit?

The most common location of these tumors is in the cerebellum, where they are called cerebellar astrocytomas. These tumors usually cause symptoms of increased intracranial pressure, headache, and vomiting. There can also be problems with walking and coordination, as well as double vision.

How does the cerebellum affect behavior?

For example, abnormalities in the cerebellum have been linked to autism, schizophrenia, and substance use disorders, and brain activation in the cerebellum has been linked to motivation, social and emotional behaviors, and reward learning, each of which can be disrupted in psychiatric disorders.

What disorders are associated with the cerebellum?

Problems with the cerebellum include:

  • Cancer.
  • Genetic disorders.
  • Ataxias – failure of muscle control in the arms and legs that result in movement disorders.
  • Degeneration – disorders caused by brain cells decreasing in size or wasting away.


Does a brain MRI show the cerebellum?

The cerebellum with surrounding skull and spinal fluid occupies the bottom 1/3 of this axial MRI image. This is an axial view, through the middle of the cerebellum above, also showing some of the temporal lobe.

What is the most common cause of cerebellar disease?

Cerebellar disease can result from a number of underlying conditions, many of which are listed in Box 91-1. The most prevalent causes of acute cerebellar ataxia are viruses (e.g., coxsackievirus, rubeola, varicella), traumatic insults, and toxins (e.g., alcohol, barbiturates, antiepileptic drugs) (see Chapter 92).
