How the Brain Works Part 1 (UCLA)

These brief videos provide an introductory appreciation of how we learn skills and information, move, think, feel, speak and remember. They are brought to you by the UCLA Brain Research Institute and by Bruce H. Dobkin, MD, who directs the neurorehabilitation program in the Department of Neurology at UCLA. The videos especially aim to reach out to students in grade school to stir their interest, and to people with disabilities in walking, using an affected upper extremity, and loss of memory from neurological diseases such as stroke, brain trauma, tumors, multiple sclerosis, cerebral palsy, Parkinsons, and Alzheimers disease.

Lettre de Londres

Je suis bien arrivée à Londres pour ma dernière année d’études de marketing à l’université. Là-bas tout le monde parle anglais ! Londres est différent de Paris. Par exemple, les bus sont rouges et certaines stations de métro semblent très anciennes.
