Learning and Memory rich research field.
What are the brain structures underlying memory?
What structure support different aspects of memory?
How do we remember and what happens when we
Primary median sternotomy technique
A skin incision is made with a scalpel that extends from the midpoint between the angle of Louis and the
sternal notch to below the xiphoid process; following this, a diathermy incision is extended through the
Median sternotomy is one of many incisions that can be made in the thorax and gives a wide view of the
thoracic cavity. Other incisions which involve the sternum, providing access to the thoracic cavity include
the hemisternotomy (upper or lo

The functions of the frontal lobes defy a simple definition.
Frontal lobe controls the behaviors that allow us to interact with our
world in a purposive manner; goal-oriented behaviors.

The standard procedure for closing the sternal incision is to place chest drains in the thoracic cavity
before using wire sutures to secure the sternum. In general, two wire sutures are placed around the
manubrium and four are placed ar
