Neurons And Hippocampus

Hippocampus/ Neuron Intro

• The definition of neurons is brain cells that
  manifest all properties of the mind. Neurons
  send and receive information. Not all neurons
  look the same. The fact that they send and
  receive information one of the few
  characteristics they share. The reason being
  that they come in different shapes and sizes.
• The word hippocampus comes from the Greek word
  hippo meaning horse and the other Greek word
  meaning sea monster. It plays an important role
  in long-term memory and spatial navigation.

Hippocampus

• The hippocampus is very closely related to the
  cerebral cortex. It is like it because it is
  paired structure with the two equal sides on both
  the left and right sides of the brain. It is
  located inside the medial temporal lobe beneath
  the cortical surface.

Neurons

• The study of neurons can be classified as ne plus
  ultra or the quantum mechanics of biology. They
  can conduct distinct signals as electro-chemical
  pulses. These are known as action potentials or
  spikes.

Hippocampus

• Its curved shape reminded early anatomists of the
  horns of a ram or a seahorse. The name was given
  to this part of the brain by a sixteenth century
  anatomists Julius Caesar Aranzi . When you have
  Alzheimer's disease, your hippocampus is one of
  the first components of the brain affected.
  Memory loss and disorientation are among the
  first symptoms. Your hippocampus is also
  responsible for emotion and learning.

More Information on Neurons

• Neurons are like the core components of the
  nervous system which is the brain, spinal cord,
  and the peripheral Ganglia. A ganglion is a
  biological mass of tissue and is usually a mass
  of nerve cell bodies. A number of specialized
  types of neurons exist sensory neurons respond
  to touch, sound, and light and numerous other
  stimuli affecting cells of the sensory organs
  that then send signals to the spinal cord and
  brain. Motor neurons receive signals from the
  brain and s spinal cord and cause muscle
  contractions and affect glands. Interneuron's
  connect neurons to other neurons within the same
  region of the brain or spinal cord.

What is a Ganglion?

• Well, in anatomy, ganglions are biological tissue
  masses, usually a mass of nerve cell bodies.
  Also, cells found in ganglions are called
  ganglion cells, though this is also sometimes
  used to refer to specifically to something called
  retinal ganglion cells.

Quick Facts
Did you know, the two cerebral hemispheres
account for 85 of the brains weight. The
billions of neurons in the two hemispheres are
connected by thick bundles of nerve fibers.
