SPM Extensions. Introduction Many SPM users have created tools for neuroimaging analyses that are based on SPM. You will find here a list of these tools classified between Toolboxes, Utilities, Batch Systems and Templates. The distinction between Toolboxes and Utilities can be blurry, but for the purposes of this page we define a toolbox to be a utility that can be completely operated via a graphical user interface.
If you notice inaccuracies or out of date links, please email the SPM manager. The SPM Developers take no responsibility for the usability of the extensions listed here.

Cambridge Research Systems - MR Safe Displays. The BOLDscreen range of "MRI compatible" MR Safe LCD monitors are ideal for presenting visual stimuli for fMRI and patient entertainment during routine clinical applications. BOLDscreen testimonials This is what our customers tell us about their BOLDscreens: The Department of Neurology at the Universitätsklinikum Hamburg-Eppendorf has a 3T Siemens Skyra. They told us: "BOLDscreen performs exceptionally and was very easy to configure. The NeuroImaging Center at the Rijksuniversiteit Groningen has a 3T Philips Intera. "BOLDscreen provides an absolutely fabulous image and our testing shows no artefacts whatsoever. " The Melbourne Neuropsychiatry Centre at the University of Melbourne has a 3T GE Signa. "We are using the BOLDscreen and it is going well.
The Durham University Neuroimaging Centre have a 3T Siemens TIM Trio. "We've got the standard BOLDscreen connected to ViSaGe and are very happy with it so far. Home · MRtrix3/mrtrix3 Wiki. [ACID/HySCO] - Hyperelastic Susceptibility Artefact Correction. What is HySCO? HySCO is an academic software for the correction of susceptibility artifacts in diffusion weighted images based on a reversed gradient based acquisition scheme.
It is developed by Lars Ruthotto and Jan Modersitzki as an add-on to the registration toolbox FAIR. HySCO requires the acquisition of a pair of images with reversed phase-encoding gradients that are oppositely affected by distortions. From the so-called "blip-up" and "blip-down" image data, HySCO estimates the field-inhomogeneity by solving a tailored image registration problem that incorporates a physical model of inhomogeneity artifacts in spin-echo MRI. HySCO's name-giving component is a special nonlinear regularization functional, which is inspired by hyperelasticity. It ensures smoothness of the field inhomogeneity and invertibility of the geometrical transformations regardless of the actual choice of regularization parameters.
A quick demo Read more J. 3.2 MRI Scan Functional Protocols | Cincinnati MR Imaging of NeuroDevelopment. This session includes 51 minutes of image acquisition and should be completed in less than one hour of total scan time. This session includes survey scan for head position and positioning image planes subsequent in subsequent scans, a reference can for calibration of the 32 channel SENSE head-coil, a 3D T1 weighted (1,2 or IR Prepped) high-resolution anatomical scan of the entire brain with spatial resolution of 1 x 1 x 1 mm. Functional MRI scanning is done using a special purpose simultaneous ASL/BOLD sequence that will allow activation maps to be computed either from the BOLD data or from the ASL data.
Alternatively, quantitative perfusion image data acquired in during language stimulation to be used as a covariate in the analysis of the BOLD data in order to correct for age dependent changes in CBF across the age span of the study cohort from birth to 18 years. List of Scans in the Functional Session (total length: 50:10.4 ) Gradient-echo, single shot EPI acquisition. Geometry: MR Protocols - CNI Wiki. This page contains an overview of several types of MRI modalities (structural, functional, and diffusion). The basic measurement protocols are described and there are links to development plans and more detailed processing strategies. There are several typical protocols users run. These protocols involve a combination of scans. We document the most widely used protocols in this list.

Simultaneous Multi-Slice EPI The CNI, in collaboration with GE, is implementing simultaneous multi-slice EPI (also known as multiband EPI, multiplexed EPI, or, as we like to call it, "mux EPI"). MultiTracer version 2. MultiTracer is a Java application for use with volumetric imaging data. MultiTracer allows: Visualization of volumetric structural data and inspection of time courses of functional data Manual editing to remove unwanted anatomic features Manual delineation of anatomic boundaries simple measures such as volumes, areas and lengths can be quantified directly boundaries can be exported for more detailed measures using other software tools creation of mask volumes corresponding to delineated anatomic strucures Current Version The current version of MultiTracer (version 2) was released on August 29, 2012.
It produces average signal timecourses for a specified epoch surrounding all events of a given type, within a region of interest. Note that if your events are very close together in time, hemodynamic responses will be overlapping; Peate does not attempt to deconvolve the response to each event to resolve this overlap, it simply does selective averaging. PEATE VERSION 3.01, October, 2013 I've recompiled Peate and fixed a few things to bring it into the modern era.
Plotting now works again out of the box. Click here to read about or download the Cocoa version of Peate for Mac OS X.

Feedback aptico: il nome è complesso, ma il principio è molto utilizzato in una categoria di dispositivi che probabilmente ti trovi in tasca anche in questo momento. Si tratta della capacità di una superficie di restituire sensazioni tattili al verificarsi di determinate azioni o eventi, come quando lo schermo dello smartphone vibra leggermente alla pressione della tastiera touch. Ora Disney Research – il programma di collaborazione informale tra la casa di Topolino e diversi laboratori di ricerca sparsi per il pianeta – sta pensando di portare la tecnologia al prossimo livello: permetterti di provare sensazioni tattili nel mezzo di uno spazio tridimensionale come una stanza vuota, grazie solo all'aria.
Aireal è il nome del macchinario, fusione dei termini air e real, e il suo scenario di utilizzo nel futuro prossimo sarà probabilmente quello dei parchi a tema di proprietà della multinazionale. Continua dopo il video. Come e perché superiamo i nostri limiti. Cosa ci spinge a decidere per una pausa, durante il lavoro? Siamo davvero stanchi, abbiamo bisogno di una ricarica? Apparentemente, ci decidiamo per un caffè o una visita ai social network quando determinati segnali raggiungono un apice: ad esempio quando sentiamo i muscoli doloranti per lo sforzo fisico, oppure se non riusciamo più a concentrarci nel leggere quella pagina.
Quando il nostro corpo o la nostra mente si sente meglio, quei 'segnali', quei 'picchi' si azzittiscono, e noi possiamo riprendere il lavoro. Per arrivare a queste conclusioni, all'istituto di ricerca sul comportamento INSERM di Parigi, hanno studiato 39 volontari utilizzando due sistemi: l'fMRI, che mappa l'afflusso di sangue in determinate regioni del cervello mentre i partecipanti compiono determinati compiti; e il MEG, che utilizza campi magnetici per seguire i segnali elettrici del cervello. I volontari sapevano che lo sforzo richiesto sarebbe cambiato durante il test, ma non era loro dato sapere quando. » Blog Archive » Sixteen is not magic: Comment on Friston (2012)
UPDATE: I’ve posted a very classy email response from Friston here. In a “comments and controversies” piece published in NeuroImage last week, Karl Friston describes “Ten ironic rules for non-statistical reviewers”. As the title suggests, the piece is presented ironically; Friston frames it as a series of guidelines reviewers can follow in order to ensure successful rejection of any neuroimaging paper. But of course, Friston’s real goal is to convince you that the practices described in the commentary are bad ones, and that reviewers should stop picking on papers for such things as having too little power, not cross-validating results, and not being important enough to warrant publication. Friston’s piece is, simultaneously, an entertaining satire of some lamentable reviewer practices, and—in my view, at least—a frustratingly misplaced commentary on the relationship between sample size, effect size, and inference in neuroimaging. Friston’s argument And: What’s wrong with the argument.
La mappa genetica del cervello in 3D. Nonostante tutti i progressi nel campo delle neuroscienze, il cervello umano nasconde ancora molti segreti. Da oggi però i ricercatori hanno uno strumento in più per studiarlo: un vero e proprio atlante che mappa la posizione e l’espressione di circa 60mila geni, proprio come fossero catene montuose o fiumi della Terra.
L’eccezionale risultato è frutto del lavoro di un’equipe di ricerca coordinata da Michael Hawrylycz dell’ Allen Institute for Brain Science, negli Usa, e, cosa ancora più importante, è accessibile a tutti. Visitando il sito Allen Brain Atlas, infatti, chiunque potrà intraprendere un viaggio virtuale nel cervello umano per scoprire com’è fatto e come lavora. I topi sono stati i primi animali per i quali è stata disegnata una mappa completa dell’ espressione genetica cerebrale. Dopo averli scansionati con una risonanza magnetica, i ricercatori hanno sezionato i cervelli sino a scomporli in 900 micro-aree di cui è stato tracciato un profilo istologico e cellulare.
