In this case the frontal lobe of cerebrum makes a self aware (introspective) decision to reject either information or modify each information to eliminate conflict. Ans) Anterior prefrontal cortex has been associated with top-level processing abilities that are thought to set humans apart from other animals. This brain region has been implicated in planning complex cognitive behaviour, personality expression, decision making, and moderating social behaviour. Ans) Medial prefrontal cortex (mPFC) is considered to be a part of the brain's reward system.

Aggression and sexual behaviour are controlled by the same brain cells in male mice – but not in females. The brain regions that contain these cells look similar in mice and humans, say the researchers behind the study, but they don't yet know if their finding has relevance to human behaviour. They discovered a set of cells within this region in male mice that controlled both aggressive and sexual behaviours. Plus other regions that are known to look different in male and female mouse brains have "considerable overlap" in the brains of women and men, she says.

When Lorenz and Leech met her second supervisor, neuroscientist Aldo Faisal, in January, they needed to discuss how best to proceed. It's trivial for humans to figure out the combinations of sight and sounds needed to activate the auditory cortex and not the visual cortex, and vice versa - the latter can be done by pairing a blank screen with the vocal acrobatics of an opera singer, the latter by pairing video of the hurly burly of Tokyo's Shibuya crossing with the drone of a test tone. In March 2015, with the help of a statistician from King's College London, Giovanni Montana, and aided by his PhD student Ricardo Pio Monti, Lorenz and Leech created an AI algorithm based on Bayesian Optimisation, a method named after the 18th-century Presbyterian minister Thomas Bayes. When Lorenz first suggested using artificial intelligence to study the human brain, Leech was immediately struck by its implications for dealing with this looming crisis.

We expect a lot from our computers these days. All this artificial intelligence requires an enormous amount of computing power, stretching the limits of even the most modern machines. Now, some of the world's largest tech companies are taking a cue from biology as they respond to these growing demands. It will allow work on artificially intelligent systems to accelerate, so the dream of machines that can navigate the physical world by themselves can one day come true.

According to a release published on Medical Express, for the first time ever, researchers have devised a way of connecting the human brain to the internet in real time. The project works by taking brainwave EEG signals gathered by an Emotiv EEG device connected to the user's head. There is a lack of easily understood data about how a human brain works and processes information. Future applications for this project could lead to some very exciting breakthroughs in machine learning and brain-computer interfaces like Elon Musk's Neural Lace and Bryan Johnson's Kernel.

It may actually be very cruel to build a functional brain inside a computer -- and that goes for both animal and human emulations. What would you say if someone came along and said, "Hey, we want to genetically engineer mentally retarded human infants! However, what today's ethics committees don't see is how the first machines satisfying a minimally sufficient set of constraints for conscious experience could be just like such mentally retarded infants. For instance, several well-funded AI developers want to recreate human intelligence in machines by simulating the biological structure of human brains.

Neurala has created patent-pending facial recognition software capable of working on very small computers, allowing it to be used on wearable devices. Neurala's founder, Massimiliano Versace, said the software works in a similar way to the mammalian brain, allowing it learn faster than traditional search technology.

Currently, artificial intelligence (AI) technologies are able to exhibit seemingly-human traits. Many existing machine learning systems are built around the need to draw from sets of data. By giving the AI multiple objects and a specific task, "We are explicitly forcing the network to discover the relationships that exist," says Timothy Lillicrap, a computer scientist at DeepMind in an interview with Science Magazine. In this test, the network correctly identified the object a staggering 96 percent of the time, compared to the measly 42 to 77 percent that more traditional machine learning models achieved.

A company set up by Elon Musk to develop advanced biotechnology enhancements for the human brain has raised $27m (£20.9m) Neuralink could be seeking as much as $100m within the next 12 months, the filing appears to state, but Mr Musk has taken to Twitter to deny that the company was actively fundraising. And although Mr Musk has been adamant that Neuralink is not looking for further funding, Bloomberg has reported that he "has taken steps to sell as much as $100 million in stock to fund the development". The company's website states it is "developing ultra high bandwidth brain-machine interfaces to connect humans and computers". The biotechnology company, based in San Francisco, is also putting out the call for "exceptional engineers and scientists".
