1. that are?

   • The core brain are a set of masses of substance grey located from each cerebral hemisphere
     • Disorders of nuclei brain
       • Hyperkinetic disorders
         • Are those in which there are movements excessive and anomalous
           • Chorea,parkinson, Hemiballismus
       • Hypokinetic disorders
         • Are those in which it is detected absence or slowness of movement
         • Huntington, Athetosis, Sydenham Chorea

2. They are closely related to the cerebral nuclei from the functional point of view

   • Core subthalamic
     • Dopaminergic neurons, has a role important in the control engine. Influences on the tracks talamocorticalesy sbre structures of the stem brain, related with the control of the musculature axial and of the March
     • Diseases
       • Hemiballismus
   • Substantia nigra
     • Dopamine = happiness
     • of way afferent and movement eye
   • Red nucleus or nucleus ruber
     • They control the muscles of the shoulders and arms

3. Amygdala nuclei

   • And storage Procesamieto reactions and emotions
   • Diseases
     • Borderline personality disorder (BPD)
     • Social anxiety disorder(SAD)
     • Depression
     • Bipolar disorder
   • Motor

4. Fluted core

   • Caudate Nucleus
     • Motor
     • Diseases
       • Obsessive compulsive disorder (OCD)
       • Deficit of attention (ADHD)
       • Depression
       • Schizophrenia
       • Athymhormic syndrome (PAP)
     • Cognitive Functions
     • Language understanding
     • Is involved in learning and memory
     • It regulates the threshold potential and feedback mechanism
   • Lenticular Nucleus
     • Motor
     • Putamen
       • Diseases
         • Tourette Syndrome(TS)
       • Is responsible for coordinating the Automatic behavior
     • Globus pallidus
       • Diseases
         • Athetosis
       • Get information from The caudate nucleus and putamen para then send it to the substantia nigra
   • Motor

5. Cloister or bulwarks

   • It is a separate thin sheet of gray matter of the side surface lenticular nucleus by the external capsule .For outside the cloister is the subcortical white matter of the insula .The function of the cloister not known
