Training Synesthetic Letter-color Associations by Reading in Color

Cited by 5 •
2014
Reading in color is a new method for training letter-color associations that are typically found only in grapheme-color synesthetes. It involves an implicit form of training that has potential for long-term associative training methods because the training is a byproduct of reading and any text can be colored.

Fluorescence Anisotropy to Determine Transcription Factor-DNA Binding Affinity
0 Views •
2025
This video describes high-performance fluorescence anisotropy that helps to monitor the interaction between transcription factors and DNA. The assay monitors the interactions of a fluorophore-labeled DNA molecule with its specific transcription factor by measuring the degree of polarization due to molecular rotation or anisotropy of the fluorophore-labeled DNA.

Rodent models of L-DOPA-induced dyskinesias are invaluable tools to identify therapeutic interventions to attenuate the development or alleviate the manifestations that emerge due to the repeated administration of L-DOPA. This protocol demonstrates how to induce and analyze dyskinetic-like movements in the unilaterally 6-OHDA-lesioned rat model of Parkinson's disease.

The 6-hydroxydopamine (6-OHDA) model has been used for decades to advance the understanding of Parkinson's Disease. In this protocol, we demonstrate how to perform unilateral nigrostriatal lesions in the rat by injecting 6-OHDA in the medial forebrain bundle, assess motor deficits, and predict lesions using the stepping test.

Here, we describe a protocol for isolation and culture of murine pulmonary endothelial cells. This method comprises mechanic and enzymatic lung tissue dissociation as well as a 2-step purification process using anti-PECAM-1 and anti-ICAM-2 antibodies conjugated to magnetic beads, which produces a pure endothelial cell population of mostly microvascular origin.
FAQs
Changing orientation tests more than whether the patient can recognize an E shape: it requires identifying the direction of its open arms. As the symbols become smaller, accurate orientation judgments indicate that the patient can resolve progressively finer visual detail. This makes the response tied to visual clarity rather than to letter-reading ability, which is important in clinical screening.
The test minimizes the need to read alphabetic characters, so patients can respond by pointing or describing the direction of the open arms. That feature reduces language and literacy demands and supports screening in children, nonreaders, and people who speak different languages. The result focuses more directly on visual performance than on familiarity with written letters.
The smallest symbol line that the patient recognizes reliably provides an estimate of visual acuity. Clinicians can record that estimate as a Snellen fraction or a decimal value, creating a standardized way to describe how clearly the patient sees. This measurement helps document screening results and identify patients whose visual performance may require further clinical attention.
The examiner presents block E symbols in different orientations, beginning with larger symbols and moving toward progressively smaller sizes. For each presentation, the patient identifies which way the open arms point, either verbally or by pointing. The examiner uses the smallest size recognized reliably to estimate visual acuity and record the screening outcome.
Patients do not need to name or read the symbol. Instead, they indicate the direction of the E's open arms by pointing or responding verbally. This response format allows the examiner to assess recognition of orientation and visual detail even when conventional letter identification is not practical, supporting use with young children, nonreaders, and multilingual patients.
They are especially useful for vision screening when reading ability, literacy, or language differences could interfere with a letter-based assessment. Clinicians can use the test with children, nonreaders, and patients who speak different languages to help detect refractive errors and other visual problems. The resulting acuity estimate provides a practical screening measure for deciding whether visual performance warrants attention.
