SfN 2010 Membership Renewal Deadline

January 14th, 2010 Bradley Monakhos No comments

”’SfN 2010 Membership Renewal Deadline”’ has been extended until January 15th. This isn’t the last day to renew your membership, but it is the last day to renew if you’re trying to Qualify for Bonus Day Registration. I’m not sure of any perks that come with being able to register one day before registration opens for the rest of the membership, but if someone knows of any, feel free to comment.

Custom Building a Computer for Science Research Compuation

December 26th, 2009 Bradley Monakhos 10 comments

I’ve finally had enough with the constant battle to own a non-obsolete computer. Who really has the money to keep trading-up about every three years. With computers, I experience buyers remorse after just a few months. My once new Macbook Pro with the screaming-fast 2.6 GHz core 2 duo processor (which warranted 2 grand of my cashola) is now just average. I can’t take it anymore. So I’ve come up with a plan. This plan will allow me to upgrade whenever I have just a fraction of the cost of a new computer. A plan that will put me at least 3 years ahead of any mere standard new computer. It will let me add another processor core whenever Intel renders my current chip obsolete; it will allow me replace any junk Nvidia graphics card that supports GDDR# and not GDDR#+1, and it will make sure that I will have the first 500 gig solid-state hard drive that costs less than 300 bucks. Most importantly, it will let me take any processor and double the GHz via overclocking.

Things I’ll Need

* 1 Chassis
* 2 CPU/Processor
* 3 Cooling Fan
* 4 Motherboard
* 5 Memory
* 6 Video Card 1
* 7 Video Card 2
* 8 Dedicated PHYSX Card
* 9 Multiple Video Card Settings
* 10 Hard Drive
* 11 Data Hard Drive
* 12 Optical Drive 1
* 13 Optical Drive 2
* 14 Sound
* 15 Network
* 16 Extra Thermal Display
* 17 Wireless 802.11B/G Network Card
* 18 IEEE1394 Card: None

Section: Chassis Chassis
Any computer that is scheduled to last around the decade is going to require the right chassis. There are a couple of important factors to consider when purchasing a shell for the components.

* Cooling
* Board Compatibility
* Stacking Ability
* Aesthetics and Durability
* Cable Management
* Drive Bays
* Tower Space
* Front Ports

After doing a bit of research I’ve decided to go with the Cosmos 1000 by Cooler Master. It has a nice combination of features which include: tool-free Structure, tree kit side panel installation, finger pressing buttons for quickly maintaining or upgrading 5.25″ drive devices, detachable aluminum HDD trays, an air intake system (dual bottom an intakes to draw in cool air and reduces system noise), 120 mm bottom Ian fans, detachable aluminum HDD, stacking feature that optimizes cooling performance.

Can Ants Count

December 6th, 2009 admin 2 comments

The following article is featured on the NPR news website, along with a nice little video.

Back to article on OneSci

Harald Wolf of the University of Ulm and his assistant Matthias Whittlinger proposed that ants have “pedometer-like” cells in their brains that count the steps they take.

How Do Ants Get Home?

Most ants get around by leaving smell trails on the forest floor that show other ants how to get home or to food. They squeeze the glands that cover their bodies; those glands release a scent, and the scents in combination create trails the other ants can follow.

That works in the forest, but it doesn’t work in a desert. Deserts are sandy and when the wind blows, smells scatter.

So how do desert ants find their way home?

Ksenija Marinkovic Lecture

November 18th, 2009 Bradley Monakhos 4 comments

Humor plays an important role in social interactions as people take great pleasure in sharing moments of suspense followed by mirth as they listen to a joke. Contributions from multiple brain areas including semantic, mnemonic, emotional and inferential are necessary to understand a joke and derive a sense of amusement, but the functional neuroanatomy and processing time course of such a network remain unknown. Prominent models commonly postulate that the punchline is appreciated as funny in two stages of integration: in the first stage the punchline is perceived as incongruous with the setup, and in the second, further consideration establishes a deeper coherence with the preceding context. Thus, amusement may result when a “twist” is successfully incorporated into the context, that is, when the initial incongruity is resolved by reinterpreting or “frame shifting”. We will discuss neural underpinnings of these processing stages by examining evidence obtained with intracranial EEG and anatomically-constrained magnetoencephalography (aMEG) in language and humor tasks. By combining high-density whole head MEG with anatomical MRI, the aMEG method allows us to estimate where the humor-specific brain activations occur, and to understand their temporal sequence. Our results indicate that coherent integration of the intended meaning and a sense of amusement may emerge from the dynamic interaction of both left and right hemispheres with special contributions from the right prefrontal region.

Neuronal signaling

Most computational models build off this ‘all or none’ assumption, and they seem to do a decent job in representing some phenomena. But why would it have to be this way? What is so special about this transient fluctuation in membrane potential, and what about it allows images and events to enter our awareness? Is it the opening of voltage-gated ion channels? Release of neurotransmitter? Rapid movement of ions? Do action potentials that originate at the hillock have different effects than those initiated in the dendrites?

Triggering memories with optogenics

October 28th, 2009 admin No comments

One of the central predictions of the Hebbian theory of learning is that memories are stored by the same neurons that were engaged during learning. Although Hebb published his famous postulate, “neurons that fire together, wire together” (paraphrasing, of course) over 50 years ago, actual evidence that both learning and memory activate the same population of neurons has largely been absent. However, new research out of the Hausser lab lends experimental support to this long-standing assumption, and also indicates that reactivation of just a fraction of these “memory neurons” is enough to conjure up full blown recall.

The Amazing GPCR Just Got Better

October 24th, 2009 admin No comments

G Protein-Coupled Receptors (GPCRs) are my favorite receptors in the whole wide world. Their versatility allows them to modulate a remarkable number of signaling pathways; environmental stimuli such as light, neurotransmission signals like acetylcholine, and hormonal stimuli such as adrenaline, all utilize GPCRs.

G-protein coupled receptors (GPCRs) are localized on plasma membranes and activated by extracellular ligands. However, recent studies have opened the door to the possibility that GPCRs exist and function INSIDE the cell — HOW THE! — is exactly what a group from Washington University in St. Louis (a.k.a. Wash-U) has been exploring…
