To what extent does cognition control emotion? Cognition and emotion are inextricably linked. The debate over their connection dates back even to Greek philosophy. Marcus Aurelius meditated “If you are distressed by anything external‚ the pain is not due to the thing itself‚ but to your estimate of it; and this you have the power to revoke at any moment” (cited in Ochsner & Gross‚ 2005‚ p.243). This statement epitomized the puzzle: Are emotions entirely subject to cognitive interpretation

The ulnar nerve is formed from the medial cord nerve roots of C7-T1. Originating in the brachial plexus‚ it descends down the arm before passing around the medial epicondyle of the elbow (the so-called funny bone) and then passes between the heads of flexor carpi ulnaris (FCU). It gives some cutaneous branches just before the wrist whilst the motor branches pass around the hook of hamate. Its motor contribution is to all small muscles of the hand except the lateral two lumbricals as well as FCU

The human eye and a camera lens have a few things in common most notably that they both use a converging lens to receive and project images. But human eyes and camera lenses have many things that set them apart from each other. “Retina Provides Color • the image an eye perceives is projected from the cornea to the retina‚ which absorbs the image and projects it to the brain. A camera projects an image on to film where it is captured and saved as a black and white image. The retina contains millions

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

base of the brain by a short stalk. Pituitary is from Latin pituita‚ meaning slime or mucus. Pathologies include hypopituitarism and hyperpituitarism. The pituitary body is in reality two glands by origin and function: Anterior Pituitary Gland (Adenohypophysis) The anterior lobe is ectodermal in origin‚ derived from an out pouching from the primitive pharynx. Posterior Pituitary Gland (Neurohypophysis) The posterior lobe is neural in origin‚derived from the out pouching of the base of the

Chapter 48 Nervous Systems Lecture Outline Overview: Command and Control Center The human brain contains an estimated 1011 (100 billion) neurons. Each neuron may communicate with thousands of other neurons in complex information-processing circuits. Recently developed technologies can record brain activity from outside the skull. One technique is functional magnetic resonance imaging (fMRI)‚ which reconstructs a 3-D map of the subject’s brain activity. The results of brain imaging and other

A special branch of linguistics‚ New medical imaging techniques such as PET and fMRI have allowed researchers to generate pictures showing which areas of a living brain are active at a given time. In the past‚ research was primarily based on observations of loss of ability resulting from damage to thecerebral cortex. Indeed‚ medical imaging has represented a radical step forward for research

bilateral upper motor neuron input (i.e. from both sides of the brain) while the ventral division receives only contralateral input (i.e. from the opposite side of the brain). - Thus‚ lesions of the corticobulbar tract between the cerebral cortex and pons and the facial motor nucleus destroy or reduce input to the ventral division‚ but ipsilateral input (i.e. from the same side) to the dorsal division is retained. As a result‚ central facial palsy is characterized by hemiparalysis or hemiparesis

What is Biological Psychology? It is the study of the physiological‚ evolutionary‚ and developmental mechanisms of behavior and experience. It is synonymous with the terms biopsychology‚ physiological‚ and behavioral neuroscience. Much of biological psychology is devoted to studying brain functioning. Physiology is the study of body processes- the dynamic of tissue and organ system of the body. It is the study of the physiological basis of human and animal behavior. Areas of Biological
