Neural engineeringNeural engineering (also known as neuroengineering) is a discipline within biomedical engineering that uses engineering techniques to understand, repair, replace, or enhance neural systems. Neural engineers are uniquely qualified to solve design problems at the interface of living neural tissue and non-living constructs (Hetling, 2008). The field of neural engineering draws on the fields of computational neuroscience, experimental neuroscience, neurology, electrical engineering and signal processing of living neural tissue, and encompasses elements from robotics, cybernetics, computer engineering, neural tissue engineering, materials science, and nanotechnology.
Transcranial direct-current stimulationTranscranial direct current stimulation (tDCS) is a form of neuromodulation that uses constant, low direct current delivered via electrodes on the head. It was originally developed to help patients with brain injuries or neuropsychiatric conditions such as major depressive disorder. It can be contrasted with cranial electrotherapy stimulation, which generally uses alternating current the same way, as well as transcranial magnetic stimulation. Research shows increasing evidence for tDCS as a treatment for depression.
Wetware computerA wetware computer is an organic computer (which can also be known as an artificial organic brain or a neurocomputer) composed of organic material "wetware" such as "living" neurons. Wetware computers composed of neurons are different than conventional computers because they use biological materials, and offer the possibility of substantially more energy-efficient computing. While a wetware computer is still largely conceptual, there has been limited success with construction and prototyping, which has acted as a proof of the concept's realistic application to computing in the future.
Rite of passageA rite of passage is a ceremony or ritual of the passage which occurs when an individual leaves one group to enter another. It involves a significant change of status in society. In cultural anthropology the term is the Anglicisation of rite de passage, a French term innovated by the ethnographer Arnold van Gennep in his work Les rites de passage, The Rites of Passage. The term is now fully adopted into anthropology as well as into the literature and popular cultures of many modern languages.
Coming of ageComing of age is a young person's transition from being a child to being an adult. The specific age at which this transition takes place varies between societies, as does the nature of the change. It can be a simple legal convention or can be part of a ritual or spiritual event, as practiced by many societies. In the past, and in some societies today, such a change is associated with the age of sexual maturity (puberty), especially menarche and spermarche. In others, it is associated with an age of religious responsibility.
ChannelrhodopsinChannelrhodopsins are a subfamily of retinylidene proteins (rhodopsins) that function as light-gated ion channels. They serve as sensory photoreceptors in unicellular green algae, controlling phototaxis: movement in response to light. Expressed in cells of other organisms, they enable light to control electrical excitability, intracellular acidity, calcium influx, and other cellular processes (see optogenetics). Channelrhodopsin-1 (ChR1) and Channelrhodopsin-2 (ChR2) from the model organism Chlamydomonas reinhardtii are the first discovered channelrhodopsins.
Secular coming-of-age ceremonySecular coming-of-age ceremonies, sometimes called civil confirmations, are ceremonies arranged by organizations that are secular, i.e., not aligned to any religion. Their purpose is to prepare adolescents for their life as adults. Secular coming of age ceremonies originated in the 19th century, when non-religious people wanted a rite of passage comparable to the Christian confirmation. Nowadays, non-religious coming-of-age ceremonies are organized in several European countries; in almost every case these are connected with humanist organisations.
PotentiometerA potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name. Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment.
