Kognitívne vedy sú väčšinou definované ako vedecká disciplína mysle alebo inteligencie. Prakticky každý úvod do kognitívnej vedy zdôrazňuje, že ide o interdisciplinárnu vednú disciplínu zahŕňajúcu psychológiu, neurovedu, lingivstiku, filozofiu, informatiku, umelú inteligenciu, antropológiu a biológiu (ukradnuté z wikipédie).

for the first time in history, a brain implant has been approved for commercial sale. you can actually buy one.

it's called neo. costs around $15,000.

the question everyone asks first: does it actually work?

here's what the implant does.

a coin-sized chip gets placed on the surface of the brain, right over the area that controls movement.

when a paralyzed patient imagines moving their hand, the chip reads that signal, sends it to a computer, and the computer drives a mechanical glove that moves for them

picking up objects, gripping utensils, handling daily tasks.

all from thought alone.

the whole surgery takes an hour and 40 minutes.

surgeons thin the skull, open a small window, and place two electrodes directly on the surface of the brain.

then they close it up, patients go home within a week.

32 patients with spinal cord injuries were implanted in a clinical trial led by huashan hospital

Deje sa mi jeden zvláštny fenomén, ktorý neviem kde môže mať príčinu

Mám to už dlhší čas a ide o že v prednej časti mozgu pociťujem akoby, ja ani neviem ako to popísať, je to taký náhly nával absolútneho šťastia, hyperfocusu a akokeby totálnej absorbcie realitou. Je ale zaujímavé, že to nie je ničím podmienené, stáva sa to keď si varím obed alebo umývam zuby. Ráno, naobed, večer, pri akýchkoľvek myšlienkach, za akýchkoľvek emócií. Príde a odíde a trvá to celé jednu sekundu. Ale je to dosť sila a chcela by som vedieť čo to je. Hľadala som na nete v súvislosti s výskumami v oblasti neurochémie a nič som nenašla, nič z hľadiska vedy, aká porucha v neutransmiteroch to je, len samé budhistické stránky. Zdôrazňujem, že vôbec nemeditujem ani sa nevenujem žiadnemu duchovnu ani nič podobné.

Nemôžem byť vhodná na nejaké pokusy?

to čo popisuješ, mi znie ako "sekundová" hypomanická fáza. s tým, že pri "klasickej" hypomanickej fáze to trvá dlhšie (niekoľko hodín, max niekoľko dní)

00000101000635330064237302326477088411970884120908841224

:D tak to fakt netuším

iba som ti napísala, ako to na mňa pôsobí z tvojho popisu (môžem sa mýliť ofc.) :)
https://en.wikipedia.org/wiki/Hypomania

klasická manická fáza to nebude, pretože tá trvá dlhšie, je sprevádzaná nespavosťou a následne sa cítiš ako shit keď odoznie

Aha, ja že si sa stým už stretla. Ja keď som mávala manické fázy, tak som počas nich bola inak dosť nabudená, ale tiež roztekaná nie veľmi šťastná.

Áno, áno, to mám teraz. A myslíš, že to je len subjektívny dojem, alebo má človek schopnosť vnímať tie veci tak naozaj?

A study published in 2017 has overturned a 100-year-old assumption on what exactly makes a neuron "fire," posing new mechanisms behind certain neurological disorders. To understand why this is important, we need to go back to 1907 when a French neuroscientist named Louis Lapicque proposed a model to describe how the voltage of a nerve cell's membrane increases as a current is applied. Once reaching a certain threshold, the neuron reacts with a spike of activity, after which the membrane's voltage resets. What this means is a neuron won't send a message unless it collects a strong enough signal. Lapique's equations weren't the last word on the matter, not by far. But the basic principle of his integrate-and-fire model has remained relatively unchallenged in subsequent descriptions, today forming the foundation of most neuronal computational schemes. According to the researchers, the lengthy history of the idea has meant few have bothered to question whether it's accurate.

The experiments approached the question from two angles -- one exploring the nature of the activity spike based on exactly where the current was applied to a neuron, the other looking at the effect multiple inputs had on a nerve's firing. Their results suggest the direction of a received signal can make all the difference in how a neuron responds. A weak signal from the left arriving with a weak signal from the right won't combine to build a voltage that kicks off a spike of activity. But a single strong signal from a particular direction can result in a message. This potentially new way of describing what's known as spatial summation could lead to a novel method of categorizing neurons, one that sorts them based on how they compute incoming signals or how fine their resolution is, based on a particular direction. Better yet, it could even lead to discoveries that explain certain neurological disorders.

For decades, scientists have debated whether the birth of new neurons -- called neurogenesis -- was possible in an area of the brain that is responsible for learning, memory and mood regulation. A growing body of research suggested they could, but then a Nature paper last year raised doubts. Now, a new study published today in another of the Nature family of journals -- Nature Medicine -- tips the balance back toward "yes." In light of the new study, "I would say that there is an overwhelming case for the neurogenesis throughout life in humans," Jonas Frisen, a professor at the Karolinska Institute in Sweden, said in an e-mail. Frisen, who was not involved in the new research, wrote a News and Views about the study in the current issue of Nature Medicine.

The researchers, from Spain, tested a variety of methods of preserving brain tissue from 58 newly deceased people. They found that different methods of preservation led to different conclusions about whether new neurons could develop in the adult and aging brain. Brain tissue has to be preserved within a few hours after death, and specific chemicals used to preserve the tissue, or the proteins that identify newly developing cells will be destroyed, said Maria Llorens-Martin, the paper's senior author. Other researchers have missed the presence of these cells, because their brain tissue was not as precisely preserved, says Llorens-Martin, a neuroscientist at the Autonomous University of Madrid in Spain. Jenny Hsieh, a professor at the University of Texas San Antonio who was not involved in the new research, said the study provides a lesson for all scientists who rely on the generosity of brain donations. "If and when we go and look at something in human postmortem, we have to be very cautious about these technical issues."

Summary:
Bodies have bioelectrical patterns that store information "memories" separately from genomic, anatomical states. These bioelectrical patterns play a huge role in developmental processes, so that being able to control them is basically like a holy grail of regenerative medicine. It also offers interesting new insights for AI and cognition.

klasicka zapletka s novym nametom:

the University of Amsterdam re-visited this fundamental issue by testing two split-brain patients, evaluating whether they could respond accurately to objects in the left visual field (perceived by the right brain) while also responding verbally or with the right hand (controlled by the left brain). Astonishingly, in these two patients, we found something completely different than Sperry and Gazzaniga before us. Both patients showed full awareness of presence and location of stimuli throughout the entire visual field -- right and left, both.
