Where is the Consciousness Brain Region?

Elisa Clement published a new article in the AR Magazine from Champalimaud Foundation, Lisbon - Portugal. 

Most scholars consider consciousness to have two components: wakefulness and awareness. Wakefulness is fairly easy to define and measure experimentally, through EEG, because the pattern of activity shown by EEG is different in brains of awake subjects, compared to subjects who are asleep.

Awareness, on the other hand, is neither easy to assess, nor to define – what exactly does it mean to be “aware” of your surroundings? Are there different stages or levels of awareness? Are there any other more accurate and objective ways of assessing awareness other than through questionnaires filled in by subjects, which is how it is often assessed?

But the most crucial and interesting question yet to be answered is the following: is consciousness generated through the orchestrated activation of multiple brain areas, or is there one particular area responsible for it?

Learning with BCIs - from Prof. Aaron Batista

A very interesting 30 minutes presentation about BCI / Machine Learning and NeuroScience explained by Professor Aaron Batista.

When we learn, the brain changes at nearly every level of organization. Synapses form and strengthen, individual neurons change their tuning properties, and cortical maps expand. My research examines how learning alters the coordinated activity of populations of neurons. This is a particularly important level at which to study learning because it is the action of populations of neurons that drive behavior, generate perceptions, and undergird our cognition.

Open Database of Live Human Brain Cells

The Allen Institute for Brain Science has added the first data from human nerve cells to the Allen Cell Types Database: a publicly available tool for researchers to explore and understand the building blocks of the human brain. This first release includes electrical properties from approximately 300 living cortical neurons of different types derived from 36 patients, with accompanying 3D reconstructions of their shape or anatomy for 100 cells, and computer models simulating the electrical behavior of these neurons. 


The database will also contain gene expression profiles, based on measurements of all genes used by 16,000 individual cells, from three adult human brains. Data from these human cells provide an unparalleled window into the intricate components, circuitry and function of the human neocortex, including features that make our brains unique.

NeuroFuse - a Brain Miracle Pills?

Neurofuse seems to have a brain miracle effect just in a few minutes. Some testimonials report the  "amazing" intense focus, mental clarity and cognitive precision results. True or false? We will wait for the answers.


Enhance Mind IQ, which has no recorded side effects in any clinical trials, was soon the target of critics who claimed it was too powerful to be sold without a prescription. Other people in academic circles insisted that Enhance Mind IQ provided an artificial edge for its users and was unfair to those who weren’t taking it. This led to it being banned from quiz shows and at many top universities as well.

Studying the Human Cerebral Cortex with Cortical Explorer

Cortical Viewer is a web-based, interactive, 3D viewer for exploring the brain cortex developed at Imperial College.

The viewer allows users to interactively explore the HCP’s Multi-modal Parcellation. Clicking on different regions brings up access to a wealth of meta-data summarising directly the extensive neuroanatomical supplementary results. ‘Sections’ refers to which broad neuroanatomical sections of the brain the region belongs to, where these sections reference how the brain was subdivided up during manual annotation.


The explorer offers several different schemes for viewing the data, for example the regions connected (or in a common section) to the primary motor cortex can be viewed either by exploding (moving) the areas, or recolouring (to fade out unrelated regions).

The Virtual Brain - Download Free

The Virtual Brain software (TVB) is a computational framework for the virtualization of brain structure and function. This is accomplished by simulating network dynamics using biologically realistic large-scale connectivity.

TVB merges structural information on individual brains including 3D geometry of neocortex, white matter connectivity, etc. and then simulates the emergent brain dynamics. The logic of TVB is the following:
  • Structural information provides certain constraints on the type of network dynamics that may emerge.
  • While these constraints limit arbitrary brain dynamics, structural connectivity provides the foundation on top of which a dynamic repertoire of functional configurations can emerge.
  • When brain structure is changed, as maturation, aging, or from damage or disease, then the brain’s dynamic repertoire changes.


TVB allows the systematic investigation of the dynamic repertoire as a function of structure. It moves away from the investigation of isolated regional responses and considers the function of each region in terms of the interplay among brain regions.

This allows us to
  • Re-classify lesions in terms of the network of nodes (regions) and connections (axons, white matter tracts) that have been damaged and to
  • Investigate the mechanisms that preserve function by understanding how regional damage affects the function of other parts of the network.

Typing-by-Brain Facebook Project

First it was Elon Musk, now Facebook. Suddenly, all the big Silicon Valley players want to get into brain tech (IEEE Spectrum). Mark Zuckerberg added his perspective on the news in a post soon after the announcement, presenting the brain-typing project as a natural evolution of Facebook’s mission to help people share their interior worlds. If they like sharing comments, photos, and videos, why not directly share their thoughts too?


In my opinion, we must invest in this BCI solution for several years to achieve a fluid and natural writing resorting solely to the identification of brain electrical impulses through non-invasive equipment.

LSD effect in Human Brain

What is the effect of LSD in Human Brain causing abnormal sensasions and hallucinations? The answer can be obtained from Imperial College London researchers, working with the Beckley Foundation, that have visualised the effects of LSD on the human brain. Also a very interesting test to do with EEG.
“Our results suggest that this effect underlies the profound altered state of consciousness that people often describe during an LSD experience. It is also related to what people sometimes call ‘ego-dissolution’, which means the normal sense of self is broken down and replaced by a sense of reconnection with themselves, others and the natural world. This experience is sometimes framed in a religious or spiritual way – and seems to be associated with improvements in well-being after the drug’s effects have subsided.”

Brain Driver - Control a Car using Your Mind

AutoNOMOS Labs is a German company that is working on a modular system for the operation of autonomous or semi-autonomous cars. 
Using AutoNOMOS, it is be possible to detect impending dangers on roads, highways, and crossings at an early stage and accidents can be prevented. Once the technology is ready, it will be introduced at first on private property and, finally, in public traffic. The project will make a significant contribution to the development of accident-free, efficient, and environmentally friendly mobility.



In the following video we can see the use of the device EPOC from the Emotiv company. By reading the brain electrical signals recorded at the level of the scalp (EEG) it is possible to identify patterns of behavior. In this particular case driver intentions are identified to turn left, turn right and also accelerate or brake


At this moment tests are being carried out on a large place as the airport runway. In my understanding this "car technology" will need time to grow up until a complete solution can be used in a real scenario within our roads.
Not advancing a date in concrete, one day will be possible to think something like: "Stop here and park on the right side!" :-)

Neuroplasticity using a Bicycle

Here is an excellent example of neuroplasticity where the brain reorganize itself by forming new neural connections throughout life. In this funny and simple experience the wheel of the bicycle was changed, reversing the direction of intention. The instantaneous result was the expected: Falls to the ground! 


But the most interesting is how our brain, after some days or weeks, is able to adapt to this new reality. Especially if you are a child! :-)
Watch this unmissable video!
