When guest-editing Radio 4′s Today Programme in December 2010, Colin Firth commissioned a studyd as one of four co-authors of an academic paper into human brains. He asked scientists to scan the brains of politicians to see if there was any difference dependent on political leaning. Publish is the the journal Current Biology the paper was hailed as a “useful contribution”.

Initially the brains of Conservative Alan Duncan and Labour’ Stephen Pound were scanned by Geraint Rees, from University College London’s Institute of Cognitive Neuroscience. The research was continued with replicationanother 90 participants; the scan showed an association between thicker areas within the brain and Liberal and Conservative attitudes. Following a repeat of the study researchers found that they were able to predict political leaning from a brain scan with 72% accuracy.

“It is a useful contribution because it builds on and extends previous work.” This is is a quote from New York University’s Professor John Jost, one of the world’s leading authorities in political psychology.”It will probably be several years before we understand the full meaning of these results. In the meantime, the field of political neuroscience could do worse than having Colin Firth as a scientific ambassador.”

In Images of Organisation, Gareth Morgan talks about learning the skill of “reading” situations. This is particularly important for people dealing with business situations. “Skilled readers develop the knack of reading the situations with various scenarios in mind and of forging actions that seem appropriate to the readings thus obtained”. The metaphor “implies a way of thinking and a way of seeing that pervade how we understand the world generally”.

Morgan wasn’t intending to categorise different types of business, rather offer different ways of looking at them. The metaphorical lens can help people understand their experiences with them.
Morgan uses eight metaphors to create “images of organization”:

  • A Machine – Businesses are often designed and operated as if they are machines, with highly visible structures and procedures. They offer continuity and security, but tend to fit people into jobs rather than allow much creativity
  • An Organism – This means seeing the businesses as behaving in similar ways to our own biological mechanisms. When the environment around us changes, so do our bodies. Successful businesses are often adaptable and open to change. This may mean that its structures and procedures are less fixed.
  • A Brain – Seeing a business as a brain means realising it has to be able to respond to change and also capable of rational thinking and intelligent change. Being open to inquiry and self-criticism often produces the ability to innovate: as Morgan puts it, businesses become “learning systems” that are able to self-organise.
  • A Culture – When you speak of businesses as cultures, we are referring to the fact that they are made up of sets of values, perspectives and principles, held and sustained by the people who work there.
  • A Political System – Businesses are not only about structures, cultures and hierarchies, they are also about politics. Politics in this context is about the social relations between individuals and groups in a business that involves authority or power. Organisational charts that plot the lines of communications between people will reveal some, but not all of the politics.
  • A Psychic Prison – This more abstract metaphor suggests that some businesses are constrained by themselves. Conventional or usual, ways of organising work and thinking about it can limit change and the adoption of alternative business strategies. Looking at the business in these terms encourages us to dig beneath the surface in order to see the restrictions real or otherwise that may be affecting the business and its ability to operate successfully.
  • Flux and Transformation – Morgan suggests that the secret to understanding businesses from this perspective lies in understanding the constant change shaping our lives. To understand a business we have to appreciate it as an ever changing thing. It grows & regenerates in order to survive.
  • A Vehicle for Domination – This metaphor introduces the idea that businesses can be or an attempt to be dominant. They can or try to impose their will on others. Again it encourages us to dig below the surface in order to understand and appreciate how business can exert power and influence.

Morgan’s framework is considered to be useful as one way of understanding business. It’s not intended to suggest fixed types of businesses. Businesses are likely to be a mixture of different metaphors, which can change over time, or according to circumstance. The metaphors can help to highlight the complexities of a business and their potential impact.

Tinnitus is a condition where the patient reports hearing sounds in one or both ears but there is no external source.

Doctors previously thought that tinnitus was generated by ear problems. However following claims by US doctors that it is possible to pinpoint the area of the brain activated when patients suffer from tinnitus it is now widely accepted that the sounds are generated in the brain. The breakthrough was made by at team at Henry Ford Hospital, Detroit who used a special scanner to map the locations in the brain.

The scan is called magnetoencephalography (MEG) and it measures the very small magnetic fields generated by intracellular electrical currents in the neuron cells in the brain.

They played various sounds until the patients agreed that that was the sound they experienced and then scanned their brains while the sound was played.

Here are just a few interesting facts about tinnitus:

  • There are approximately 2.3 million sufferers in the UK with moderate or severe tinnitus
  • Tinnitus noise can beat in time with your pulse
  • Most people experience brief periods of tinnitus after long exposure to loud noise

The results for the MEG imaging showed that those who only experienced tinnitus in one ear the greatest amount of activity was in the auditory cortex on the opposite side of the brain. However those with tinnitus in both ears brain activity was in both sides of the brain, with greater activity appearing in the opposite side of the brain to the ear with the strongest perception of tinnitus. Another part of the brain that was showing high levels of activity on these scans was the lmbic system that governs how we react to things.

There has always been suggestions that alcohol in moderation is good for your health but the latest theory is that a dose of alcohol could be a good treatment for people with head injuries.

The basis of this is the discovery that people are less likely to die following brain trauma if they have alcohol in their blood. The reason for this could be that alcohol dampens the body’s inflammatory response to injury. However doctors do stress that alcohol can create medical complications and is a contributory factor to many accidents.

Experts are warning that people should not interpret these findings as an excuse to drink more alcohol. These findings raise the possibility of administering ethanol to patients with brain injuries to potentially improve their outcome. The amount of alcohol consumed appears to be important factor as too little and there is no effect, too much and the beneficial effects are lost. With the right dose, alcohol stops the cascade of swelling, inflammation and further destruction of brain cells, known as secondary brain injury.

These findings seem to suggest that although alcohol helps one problem it creates another, so the question is if the benefits outway the risks?
