Course Syllabus

In this section, we will discuss the different types of registration and how one would go through processing a multi-sequence MRI scan, as well as wrapper functions that make the process much easier. We also cover interactive exploration of brain image data and tissue-level (white/gray matter and cerebrospinal fluid (CSF)) segmentation from a T1-weighted image.

Neurohacking Caffeine, alcohol, over the counter medicine, and other drugs are all forms of neurohacking. Every one of these substances alters or "tricks" the brain into desirable conditions. When ingesting caffeine, the brain is fooled into thinking the body has energy and keeps the consumer awake. The brain's neurons naturally produce adenosine as a byproduct which is monitored by the nervous system. Once the level of adenosine is at a certain point, the body will feel tired. Caffeine acts as fake adenosine and binds to the body's receptors. However, instead of disappearing, it blocks the adenosine receptors so the brain's stimulants, dopamine and glutamate, can work more freely. Since neurohacking is the interference with the structure and function of neurons, caffeine consumption is in fact a neurohack. Similarly, other substances that affect the brain and functions of neurons are also neurohacks.
Neurohacking Neurohacking is the colloquial term for (usually personal or 'DIY') neuroengineering. It is a form of biohacking (qv) focusing on the brain and CNS. Strictly speaking it is any method of manipulating or interfering with the structure and/or function of neurons for improvement or repair.
Neurohacking The term neurohacking is also used for a method of attempting to retrieve information from the brain (such as passwords, locations, etc..) without consent; presently no technology exists for such a tactic. The concept has been used much in science fiction (e.g. the film "The Matrix"). In data retrieval, some sort of brain–computer interface (BCI) is typically used, where the brains neuron synapses are somehow captured or recorded to be processed for information. Promoters of this concept generally refer to the MRI (magnetic resonance imaging) or MEG (magnetoencephalography) to support the plausibility of this concept. Although some sort of neuroimaging could someday be used, the accuracy of any present day method is not nearly close enough. For instance, it is assumed that neurohacking requires detection of the state of individual neurons (approximately 1 micrometer diameter) while the resolution of the MEG is several thousand neurons and other imaging systems may be even larger. It is estimated that usable neurohacking of this type is still many decades away.
Neurohacking Current research focus on the nature and development of intelligence and how to increase or improve it. The works of Dr. Herman Epstein, Joseph LeDoux, Alex Ramonsky, Frederick Starr and David Barker are influential. The ethical basis of Neurohacking for health is that it should be practiced strictly with informed consent.
Neurohacking The main goal of neurohacking is optimal mental health. Other goals include damage repair, simulated reality, prevention of disease and augmentation of abilities or of intelligence overall. It utilises information and technology mainly from the fields of epigenetics, bio/neurofeedback, psychopharmacology, biological psychology and functional analysis, but many practitioners also employ physical exercise, nutritional guidelines, vitamins & supplements, meditation and/or self-hypnosis. Some avoid all neuroactive substances including caffeine, alcohol, food additives and fast-release sugars.
Neurohacking Alcohol is an example for a form of neurohacking which affects multiple neurotransmitters instead of just one. This is because alcohol is a fat soluble molecule. Since lipids are a major component of cell membranes, alcohol is able to enter the membranes of neurons and change their properties. Specifically, alcohol inhibits the glutamate receptor function, enhances GABA receptor function, as well as raises dopamine and endorphin levels. This causes all sorts of reactions, including liveliness and excitement. Alcohol also causes one to lose their anxieties, because of the effect of alcohol on GABA receptors. After alcohol affects the system, it causes the body to go through what is called neurotransmitter rebound. This is because when alcohol takes effect, it overuses the GABA system, so when it wears off, the GABA system makes the body feel restless, resulting in its severe withdrawal symptoms.

Introduction to Outer Space Introduction to Outer Space is a pamphlet about space exploration edited by the White House the 26 March 1958. At first, a report of the President's Science Advisory Committee presided by Dr James R. Killian in the aftermath of the Sputnik 1 launch, Dwight D. Eisenhower found it so informative and interesting that he decided to make it available to everybody for 15 cents. It presents in simple terms to the layman the future of space exploration.

Introduction (writing) Keeping the concept of the introduction the same, different documents have different styles to introduce the written text. For example, the introduction of a Functional Specification consists of information that the whole document is yet to explain. If a Userguide is written, the introduction is about the product. In a report, the introduction gives a summary about the report contents.

An Introduction to Old Norse An Introduction to Old Norse is a textbook written by E. V. Gordon, arising from his teaching at the University of Leeds and first published in 1927 in Oxford at The Clarendon Press. It has been reprinted several times since. The Second Edition was revised by A. R. Taylor, Gordon's former student and, indirectly, his Leeds successor. The book is commonly accepted as a standard text in the English-speaking world for studying Old Norse. It includes a long introduction, a short grammar of Old Norse, a glossary, an index of names and selections from the "Poetic Edda" as well as a number of other sagas (all in Old Norse).
Introduction to a Waltz Glenn Miller introduced the instrumental before the performance: "'Introduction to a Waltz' has quite an introduction-–-187 bars to be exact, with 8 bars of 'waltz' near the end of the tune." The performances featured Billy May on trumpet, Tex Beneke on tenor saxophone, Chummy MacGregor on piano, and Moe Purtill on drums.
