The Blue Brain Project by Serge Achildi The Blue Brain Project is an attempt to create a synthetic brain by reverse-engineering the mammalian brain down to the molecular level. An effort to create the first computer simulation of the entire human brain‚ right down to the molecular level‚ was launched on June of 2005. The hope is that the virtual brain will help shed light on some aspects of human cognition‚ such as perception‚ memory and perhaps even consciousness. The "Blue Brain" project‚ a

Boy Scouts. All of my dive training and practice dives have led to this day. Will I be successful? The day starts at 7:45 am. The dive group meets at the flagpole to recite the Pledge of Allegiance and say Grace. Upon dismissal‚ we proceed to the Mess Hall for a hearty breakfast of eggs‚ bacon‚ and cereal. Upon taking the last bite‚ I thought to myself‚ I hope this is not my last meal. If so‚ I wish we were eating spaghetti for breakfast. After clean-up‚ Terrence‚ our Dive Master‚ leads us to

However you will not need to submit your answers to these questions‚ only the questions on the worksheet ( see below). Submit your answers as a word document to the Week 4 dropbox 1. Define a reflex and list the components of a reflex arc. The reflex arc is the nerve pathway involved in a reflex action including at its simplest a sensory nerve and a motor nerve with a synapse between. The components are receptor‚ sensory neurons‚ motor neurons‚ relay neurons‚ and effector. 2. Describe

experimented on to understand how learning worked. The experiment started with shocking the Aplysia snail to teach it of the dangers of its new environment. When the snail’s siphon is touched‚ it triggers a defensive mechanism‚ a withdrawal reflex. It is this reflex that lets scientists know the Aplysia has formed new memories as it is on high alert and fearful from its past experiences of getting shocked. The scientists compared two snails‚ one with past experiences of being shocked and one that had

neuropathies damage peripheral nerves. Which component of the reflex arc is most likely to be damaged in Nick’s situation? I think a lot of Nicks reflex arc damage would begin at the sensory neuron. Stimuli are still triggering the receptor‚ but the information isn’t traveling along the damaged sensory neuron to continue the arc to the integrating centers‚ motor neurons‚ and effectors‚ though the damage could be further along in the reflex arc providing basically the same symptoms. D. Which division

Chapter 15 Signal Transduction 1) Endocrine‚ paracrine ‚ autocrine signaling‚ and cell-cell contact (Fig. 15-2). Endocrine signaling is long distance signaling. An example would be pancreatic cells secreting insulin. Paracrine signaling is for close proximity. An example would be a nerve cell releasing neurotransmitters. In autocrine signaling the cell that produces the ligand also contains the receptor for that ligand. This is how cancer cells work. In signaling by plasma membrane attached
