The hippocampus is involved in the storage of long-term memory, which includes all past knowledge and experiences
Limbic system that is responsible
for changing the emotional functions
and stress levels of the body.
The human brain is dived down the middle into two hemisphere, with each half performing a fairly distinct set of operations.
The brain's right hemisphere controls the muscles on the left side of the body, while the left hemisphere controls the muscles on the right side of the human body.
The two hemisphere communicate information to each other through the thick corpus callosum that connects them.
Differing severity of TBI
what is TBI?
Traumatic brain injury, often referred to as (TBI) is a condition resulting from a blow, bump or jolt to the head that disrupts the normal function of the brain
Happy messengers
These three areas effect different body functions,
such as movement, memory, sleep, mood, pleasurable reward, behavior and cognition.
Vital chemicals carry messages between brain cells. They allow brain cells to talk to one another.
The nerve centre receive input from happy messengers and sad messengers.
The structure of the brain is an incredibly complex organ. The brain is protected by a bony covering called the cranium, which consists of three layers.
Techniques used:
Computed Tecnography (CT)
Diagnosing Brain Trauma
Anyone can be affected
Magnetoencephalography (MEG)
Arachnoid membrane
the middle layer of tissue
Magentic Resonance imaging (MRI)
The effects of Trauma on the Brain
Neuroimaging consist of a variety of brain scans. Neuroimaging scans generate images of the brain.
Dynamic CT or Dynamic MRI
Dura Mater
the outer layer
The patient will swallow a
substance before and during the scan if the patient seems to be using a lot of the substance in one area of the brain it can help provide information or detect the Trauma
The emotional wounds these traumatic events cause on the brain, are also known as post-traumatic stress disorder (P.T.S.D).
Flow sensitive MRI (FS MRI)
Pia Mater
closet to the surface
Position Emission Tomography (PET)
The amygdala, the hippocampus, and the ventro medical prefrontal cortex play a role in triggering the typical symptoms of PTSD
Effects of Trauma on Hippocampus
Chemical messengers or neurotransmitters are constantly active going between cells
Emotional brain instincts are more sensitive depending on female or male
The most significant neurological impact of trauma is seen in the hippocampus. PTSD patients show a considerable reduction in the volume of the hippocampus
Functions of the Brain
Largest part of the human brain
Hypothalamus, the hippocampus, and the amygdala work to create emotion
Emotions are controlled by the levels of different chemicals which are present and active in the brain
The right hemisphere and the left cerebral hemisphere. The right controls the left side
of the body, while the left cerebral hemisphere controls the right.
Cerebrum controls the body temperature, movement, vision, hearing, touch, learning, problem solving and emotions
The brain stem controls the essential body functions, breathing, cardiac function and muscle movements.
Cerebelllum is located at the back of the skull in vertebrates. In front lies the brain stem, which serves as the body's main control panel that transmit messages between the brain and the rest of the body.
