Vision: Light and Neural Activity May 3 2010
Description
The process of vision begins when photons of light strike photoreceptive cells in the retina and are translated into electrical signals. This illustrated explanation demonstrates how these neural signals travel through cerebral fibers to the visual cortex. It is here that the information is processed and transformed into the images we perceive.
Original title
ראייה - אור ופעילות עצבית (3 במאי 2010)
תהליך הראייה מתחיל כאשר פוטונים של אור פוגעים בתאים רגישים לאור ברשתית העין ומתורגמים לאותות חשמליים. הסבר מאויר זה מציג כיצד האותות העצביים עוברים דרך סיבי המוח אל קליפת המוח הראייתית, שם מתבצע עיבוד המידע שהופך לתמונה שאנו תופסים.

Daniel Asks: Why Are We Afraid of the Dark
Credit: מכון דוידסון לחינוך מדעיThe fear of the dark is an ancient evolutionary survival mechanism designed to protect us from predators lurking in places we cannot see. Our brains tend to fill in missing visual information with our imagination, which triggers a sense of danger and anxiety in children and adults alike. Understanding the evolutionary roots of this fear helps us confront it in a more rational and calming manner.2:48

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
