The Ionic mechanism and propagation of action potentials. The action potential is the result of a large‚ sudden increase in sodium permeability of the membrane. The resulting rush of sodium ions into the membrane and accumulation of positive charge on its inner surface drives the potential towards Ena. This is followed by repolarisation‚ whereby there is a large increase in the membranes permeability to potassium ions‚ hence the membrane returns to Ek. Explanation of the (ionic) mechanisms underlying

Thresholds * An Absolute Threshold is the lowest amount of stimulus needed to notice it 50% of the time. * For example‚ you turn down the radio to a point where you only hear the faint sound half the time. Then that loudness (decibel) is your absolute threshold for sound. * Signal detection theory predicts when we will detect weak signals (measured as our ratio of “hits

Milk consumption in US has decreased that’s why the Milk Industry Foundation pumped $44 million into an advertising campaign to promote milk drinking (“Got Milk?”) We each put our personal “spin” on things as we assign meanings consistent with our own unique experiences‚ biases

Watching Sensation and Perception on Discovery Psychology with Philip Zimbardo greatly enforced material that we have learned in class. As the film begins some questions are posed such as how is our brain tricked by visual illusions and what makes a star quarterback miss an easy pass? These questions and many more where discussed and answered throughout the film. The first explanation given as to why our brain might be tricked by the world around us is because of the limitations to our sensation

sensory impulses to interpret them in the brain as an image and allow them to make out objects. Researchers have also studied how sensitive our senses are by using an absolute threshold and difference threshold. Absolute threshold testes how we can detect the smallest amount of energy‚ like a flashing light while difference threshold tests how we are able to detect if there is a difference in two objects. We are able to adapt to certain sensory like‚ wearing clothes‚ the stimulus signal is
