In schizophrenia research, a path to the brain through the nose

A significant obstacle to progress in understanding psychiatric disorders is the difficulty in obtaining living brain tissue for study so that disease processes can be studied directly. Recent advances in basic cellular neuroscience now suggest that, for some purposes, cultured neural stem cells may be studied in order to research psychiatric disease mechanisms. But where can one obtain these cells outside of the brain?

New gene that regulates body weight discovered

While studying a brain protein related to the involuntary body movements that are side effects of drugs used to treat Parkinson's disease and schizophrenia, a pharmacy professor discovered that the protein also plays a role in regulating body weight.

Top 5 great apps that will run great on the iPad 2 and iPhone

The iPad 2 and iPhone 4S are the new mainstays on the mobile market, both of them dominating in sales in both the tablet and smartphone niches, and thanks to Apple’s marketing and great developer tools, the iTunes market is filled with apps for the iOS operating system. The iPad 2 and iPhone 4S got dual core processors and a few other hardware upgrades (like a camera on the iPad 2), so here are a few apps you should try in order to get the most out of either of these two devices:

 

You can get all great iPad 2 and iPhone 4S apps .

 

  • iMovie. iMovie is the official video editing application from Apple, and it’s pretty impressive seeing it in action on a tablet. The app requires a dual core processor and 512 MB of RAM, so it will only work on the iPad 2 and iPhone 4S, so if you have one of them, be sure to check it out. You can film something with the integrated camera or open any video file and start editing: remove frames, add special effects and filters, create a collage, and much more.

 

  • Apple iWork Suite. The popular (among Mac OS X users) iWork Suite is Apple’s own answer to Microsoft’s Word, Excel and PowerPoint combo from the Office suite, and the programs are really great, too. With Pages, Numbers and Keynote, you can open and edit any kinds of documents and spreadsheets, create presentations, documents and graphs, export to different file formats and output to an external display or projector and more. All of that from the comfort of your iPad or iPhone.

 

  • Evernote. Evernote is the leading note taking app for the iPad and iPhone (as well as Windows and Mac OS X, as a matter of fact), and having it installed is pretty much a must if you always save interesting stuff from the Web, take photos and videos and want to organize them with notes and descriptions, or simply want to be able to save a written note every time a good idea pops in your head. You can then sync your iPad or iPhone with your online account or your computer, so you always have access to your notes and never lose them.

 

  • Spotify. Spotify is the leading music streaming app for Android and iPhone (it started out in Europe, but has recently become available in the US and Canada, as well), and with the newest version, you can get access to over 15 million songs by most of the popular artists in the world, with new ones added every single day. Spotify Radio allows you to create stations that steam songs from the artists and albums you choose, and you get unlimited playback and skips (for the moment). If you want to save the songs to your iPad or iPhone and listen to them offline, you’ll need a Premium account, which is totally worth the cost – it’s like iTunes, only better!

 

  • VideoSurf. If you heard of or actually like Shazam, the app that lets your phone recognize a song using a short recording of it (using the phone/tablet’s microphone), well then you’ll like VideoSurf, which brings the same functionality for videos. You can use VideoSurf to quickly find out what show or series is on TV at the moment by recording a few seconds of it and letting the app do its job. Obviously, it will work on the iPhone 4S and the iPad 2, both of which have a camera on the back, but it won’t work on the first iPad.

Obviously, these aren’t the only apps that will bring out the best in your iPad 2 or iPhone 4S, and if you want to find more of them, just do a search online or on the iTunes market – you are guaranteed to find something you like in the 500,000 apps that are published there.

Brain cell malfunction in schizophrenia identified

Scientists have discovered that DNA stays too tightly wound in certain brain cells of schizophrenic subjects. The findings suggest that drugs already in development for other diseases might eventually offer hope as a treatment for schizophrenia and related conditions in the elderly.

Researchers discover clues to developing more effective antipsychotic drugs

Researchers have identified the pattern of cell signaling induced by antipsychotic drugs in a complex composed of two brain receptors linked to schizophrenia. The discovery should allow researchers to predict the effectiveness of novel compounds for the treatment of schizophrenia and other serious mental disorders and may accelerate the development of better antipsychotic drugs.

Mental illness: Early-life depression and anxiety changes structure of developing brain

New research identifies the brain chemicals and circuits involved in mental illnesses like schizophrenia, depression, and anxiety, giving potential new directions to their treatment. In addition, research with children shows that early-life depression and anxiety changes the structure of the developing brain.

How cannabis causes 'cognitive chaos' in the brain

Cannabis use is associated with disturbances in concentration and memory. New research by neuroscientists in the UK has found that brain activity becomes uncoordinated and inaccurate during these altered states of mind, leading to neurophysiological and behavioral impairments reminiscent of those seen in schizophrenia.

Differing structures underlie differing brain rhythms in healthy and ill, virtual modeling reveals

Virtual brains modeling epilepsy and schizophrenia display less complexity among functional connections, and other differences compared to healthy brain models, researchers report. The researchers worked backward from brain rhythms -- the oscillating patterns of electrical activity in the brain recorded on electroencephalograms -- from both healthy and ill individuals.

Schizophrenia genetics linked to disruption in how brain processes sound

What links genetic differences to changes in altered brain activity in schizophrenia is not clear. Now, three labs have come together using electrophysiological, anatomical, and immunohistochemical approaches -- along with a unique high-speed imaging technique -- to understand how schizophrenia works at the cellular level, especially in identifying how changes in the interaction between different types of nerve cells leads to symptoms of the disease.

Atypical antipsychotics may aid symptons for some off-label uses, but not others

Atypical antipsychotic medications, developed to treat schizophrenia and bipolar disorder, are frequently prescribed for many off-label uses. A new study finds that medical evidence suggests the drugs are effective in reducing symptoms for some off-label conditions, but not others.

Atypical antipsychotics appear to be effective for only few off-label uses, study suggests

A review of previous studies suggests that even though atypical antipsychotic medications are commonly used for off-label conditions such as behavioral symptoms of dementia, anxiety, and obsessive-compulsive disorder, these medications are effective for only a few off-label conditions, and that the benefits and harms of these medications for these uses vary, according to a new article.
