- What Is It? Strokes can damage brain tissue in the outer part of the brain (the cortex) or deeper structures in the brain underneath the cortex. A stroke in a deep area of the brain (for example, a stroke in the thalamus, the basal ganglia or pons) is called a lacunar stroke.

Basal ganglia disease The basal ganglia is a collective group of structures in the brain. These include the striatum, (composed of the putamen and caudate nucleus), globus pallidus, substantia nigra, and the subthalamic nucleus.hough motor disorders are the most common associated with the basal ganglia, recent research shows that basal ganglia disorders can lead to other dysfunctions such as obsessive compulsive disorder (OCD) and Tourette syndrome.

Frontal lobe injury The portion in color is the left frontal lobe, damaged in Phineas Gage's accident. The frontal lobe of the human brain is both relatively large in mass and less restricted in movement than the posterior portion of the brain. It is a component of the cerebral system, which supports goal directed behavior.

- 3. http://www.tutis.ca/NeuroMD/index.htm 23 March 2013. Introduction The basal ganglia and cerebellum are sub-cortical structures that receive input from wide areas of the cerebral cortex and direct their output, through the thalamus, back to more precisely defined regions. The cerebellum corrects the errors in each movement command and imparts motor skills.

- MRI results most commonly revealed abnormalities in the meninges, the cerebral cortex, basal ganglia, and thalamus (Table 4 and Figure 1, panels B-D). The findings, which challenge the classical view of basal ganglia function, were published online in Nature on Jan. Pathological hallmarks of Parkinson's disease are destruction of dopaminergic neurons in the basal ganglia, especially the substantia nigra, and the presence of Lewy bodies within nerve cells. Parkinson's disease: mitochondrial molecular pathology, inflammation, statins, and therapeutic neuroprotective nutrition.

- Cerebral Cortex. The cerebral cortex is tissue that covers the cerebrum. A thick band of nerves (corpus callosum) connects the right and left cerebral cortex sides. The cerebral cortex is responsible for most higher order or intellectual brain functions such as thinking, reasoning, judging, planning, voluntary movement, and overall behavior. Injury to this area of the brain can impair judgment, cause dramatic personality change, and create problems with attention and focus. Cerebral Cortex Functions. Thinking

Chapter 1: The Brain Other Parts of the Brain-Deep in the cerebral hemispheres are groups of neurons called basal ganglia (see Figure 6). The basal ganglia consist of the caudate nucleus, the putamen, the pallidum, and the substantia, nigra. The basal ganglia appear to be primarily important in the control of movement.

Cognitive Skills of the Brain The frontal lobe links and integrates all components of behavior at the highest level. Emotion and social adjustment and impulse control are also localized here. Injury to parts of the frontal lobe may cause an inability to move part of the body or the whole side of the body. Speech may become halting, disorganized or be stopped except for single explosive words. Personality may change. Social rules of behavior may be disregarded.

Basal ganglia Learn about this topic in these articles: structure of the brain. ...within the cerebral hemispheres, large gray masses of nerve cells, called nuclei, form components of the basal ganglia. Four basal ganglia can be distinguished: (1) the caudate nucleus, (2) the putamen, (3) the globus pallidus, and (4) the amygdala.

Thalamus Injury A thalamus injury refers to an area that is directly above your brain stem but below your cortex. The thalamus receives visual, auditory and somatosensory signals from various areas of your brain. It then routes these signals to a specific area in the cortex to be further processed.

- Basal nuclei: A region located at the base of the brain composed of 4 clusters of neurons, or nerve cells. This area of the brain is responsible for body movement and coordination.The groups of neurons most prominently and consistently affected in Huntington disease -- the pallidum and striatum -- are located in the basal nuclei.The pallidum is composed of structures called the globus pallidus and the ventral pallidum while the striatum consists of the caudate nucleus, putamen, and ventral striatum.). The basal nuclei are also called the basal ganglia.

The HOPES Brain Tutorial (Text Version) The major divisions of the basal ganglia are the caudate nucleus, putamen, globus pallidus and substantia nigra. Caudate Nucleus^ The caudate nucleus is a collection of neuronal bodies that connects to many parts of the brain. Together with the putamen, it comprises the neostriatum.

Basal ganglia The basal ganglia (or basal nuclei) comprise multiple subcortical nuclei, of varied origin, in the brains of vertebrates, which are situated at the base of the forebrain. Basal ganglia nuclei are strongly interconnected with the cerebral cortex, thalamus, and brainstem, as well as several other brain areas.he largest component, the striatum (dorsal and ventral), receives input from many brain areas beyond the basal ganglia, but only sends output to other components of the basal ganglia. The pallidum receives input from the striatum, and sends inhibitory output to a number of motor-related areas.

- There was damage to localized areas of the primary motor cortex in the left cerebral hemisphere. There was damage to localized areas of the primary motor cortex in the right cerebral hemisphere. There was damage to localized areas of the premotor cortex in the left cerebral hemisphere.fter Joe has a stroke, his doctor asks Joe to touch his right pointer finger to his chin—but Joe is unable to move his right hand. However, when the doctor stimulates Joe's pointer finger with a painful stimulus, Joe's muscles quickly move his hand away from the stimulus.

- Brodmann Areas. Over a lifetime, the various parts of the brain that control the body's movements can suffer damage from various causes, such as head injuries, strokes, and degenerative brain diseases. One typical example is what happens when one side of the motor cortex is completely destroyed by a stroke.Because of crossed control, this centre normally controls the voluntary movements on the opposite side of the body.n 1870, Hitzig and Fritsch electrically stimulated various parts of a dog's motor cortex. They observed that depending on what part of the cortex they stimulated, a different part of the body contracted.

Top 20 Doctor insights on: A Stroke That Damages Parts Of Your Amygdala Would Have What Effects A stroke that damages parts of your amygdala would have what effects - A stroke that damages parts of your amygdala would have what effects? Fear itself. The amygdala is located in both temporal lobes. One of the chief functions is coordination of perception with fearfulness. Damage to the amygdala can have either stimulatory (fear-enhancing) or inhibitory (fear-negating) effects; either of which can be quite impairing. Other aspects of mood and behavior can be affected. Epilepsy is not infrequently a byproduct of amygdalar damage.

Know your brain: Pons This part of the pons is now referred to as the basal or basilar pons; not only is it the most distinct area of the pons, it is also one of the more recognizable areas of the brain. Posterior to (behind) the basal pons is an area sometimes called the dorsal pons or pontine tegmentum. Much of this area is also considered part of the reticular formation. The pontine tegmentum includes the tissue between the basal pons and the fourth ventricle; the pons makes up the floor of the fourth ventricle.

Lacunar Stroke Print Share. Strokes can damage brain tissue in the outer part of the brain (the cortex) or deeper structures in the brain underneath the cortex. A stroke in a deep area of the brain (for example, a stroke in the thalamus, the basal ganglia or pons) is called a lacunar stroke. These deeper structures receive their blood flow through a unique set of arteries.
