Or it may be that you are low on acetylcholine.” Acetylcholine (ACh) is a major modulator of brain activity in vivo and its release strongly influences attention. If we could visualize when and where ACh is released, we could more fully understand the large trial to trial variance found in many in vivo recordings of spike activity, and perhaps correlate that to attentional and behavioral states mediated by ACh transmission. Back in grad school, when I was desperately trying to figure out what biological question to answer with my GluSnFR glutamate sensor, I ended up in a meeting with Kleinfeld, his grad student Lee Schroder and Palmer Taylor. We plotted a strategy to make a FRET...

A gallon of ice scream in one sitting is not unheard of. But people who think deeply about such things asked themselves: why don’t they (people under stress) gorge on veggies? And what is the nature of the connection between stress and obesity? Is it simply overeating equalsobesity, or is there a deeper connection, involving the brain? After all, stress is a mind thing.The physiology of acute stress Almost every physiological action in our body is controlled by two systems: the autonomic nervous system, and the endocrine system. The autonomic nervous system has this name because it is, well, autonomic: it marches to its own drum, if you will, independently of ...

Many confuse this with multiple sclerosis. Multiple sclerosis is a central nervous system disorder affecting the insulation (myelin) on nerve cells in the brain and spinal cord. In contrast myasthenia gravis is a muscle disease where transmission of electrical impulses to the muscle fail. This results in the muscle not contracting fully, resulting in weakness. This condition can selectively affect the eye muscles, muscles of the head and neck or be generalized affecting all muscle, including the diaphragm. If the diaphragm is involved, patients can have varying degrees of breathing problems, including respiratory failure. Myasthenia gravis (MG) is the standard model of a neurological autoimmune disorder. In autoimmune diseases, the b...

After all, the first of you just got on Social Security. And what about those memory lapses? In your heart of hearts, are’nt you scared just a little bit? If you are not—read on. Here are some sobering statistics. · More than 5 million Americans are estimated to have Alzheimer’s disease or AD today. It is projected that 14.3 million Americans will have the disease by mid-century: a 350 percent increase from 2000, when there were 4 million people with the disease. Reason for the expected explosive growth: a tidal wave of aging baby boomers turning old geezers. In the United States, AD was the 7th leading cause of death in 2004 , with 65,829 number of deaths (and risin...

He did well, thank you. But when he told me about this feat of studiousness, I was wondering: how much is he going to retain one day after the test? I seem to recall from my college days that taking a test after an all-nighter was actually fraught with a lot of fuzzy thinking and faulty memory. Have you ever taken a test, and later asked yourself “how could I make such a stupid mistake”? Or “how could I forget that”? Perchance to sleep Sleep is an essential activity in our daily life. Since time immemorial sleep was associated with healing and healthfulness. Lack of sleep was associated with hallucinations and psychic torment. Just ask Lady Macbeth, walking all night, ...
