Bushra Hanaif Professor Kristen Przyborski BI 121-02 April 14‚ 2013 1) In the 1940s‚ some physicians prescribed low doses of a drug called dinitrophenol (DNP) to help patients lose weight. This unsafe method was abandoned after a few patients died. DNP uncouples the chemiosmotic machinery by making the lipid bilayer of the inner mitochondrial membrane leaky to H+. Explain how this can cause weight loss. In a coupled reaction‚ an exergonic reaction provides the energy needed to drive an endergonic

brain three of those devices are fMRI (Functional Magnetic Resonance Imaging)‚ MEG (Magnetoencephalography)‚ and the EEG (electroencephalogram) - which is the most common one. The fMRI is an object that measures the brain’s blood flow; it also helps look at neural activity. The MEG is a device that helps capture magnetic fields produced by the brain’s neural activity. The last one is an EEG that is used to record electrical activity made by neural firing. A disease associated with the parietal lobe is

When I think of biofeedback I think about meditation and yoga‚ this is a technique that you can use to learn to control your body and your mind. It can help you to stay focused and relaxed in a stressful or non-stressful situation. This type of feedback can help you make subtle changes in your life such as reducing pain. It also gives you the power to use your imagination to control your body‚ and can often help with your physical performances and any health issues that you may have. There are many

1. Introduction: Modifying the human body or enhancing our cognitive abilities using technology has been a long-time dream for many people. An increasing amount of research tries to link the human brain with machines allowing humans to control their environment through their thoughts. Research on BCIs began in the 1970s‚ but it wasn’t until the mid-1990s that the first working experimental implants in humans appeared. Following years of animal experimentation‚ early working implants in humans now

Sleep spindles Stage 3 Higher peaks and lower valleys of waves Stage 4 Slower and more regular‚ least responsive to outside stimulation The Four Stages of Sleep EEG Stages 2‚ 3‚ and 4 together are often referred to as slow-wave sleep. Stages 3 and 4 together are often referred to as delta sleep. The progression of EEG stages changes during a typical night’s sleep: each cycle is about 90 minutes long. As the night progresses less time is spent in stages 3 and 4 and more is spent

INTRODUCTION Although EEG is designed to record cerebral activity‚ it also records electrical activities arising from sites other than the brain. These unwanted chunks of electrical activity are termed artifacts and may be divided into physiological and non-physiological artifacts. Physiological artifacts are generated from sources other than the brain (i.e.‚ any other part of the body like the eyes‚ other voluntary and involuntary muscles) and involve head or limb motion and muscular tension.
