( E and F) The behavioral performance functions (both crows and average) indicated whether they judged the first test stimulus (after the delay) as containing the same number of items as the sample display (“% same as sample”). ( D) Average performance (error bars represent SEM) of both crows to the standard and the control conditions during the recording sessions. ( C) Behavioral performance (percent correct) for both crows in the DMS task over all recording sessions (chance level = 50%). The physical appearance of the displays varied widely for the same quantities (see details in Table 1). ( B) A small subset of the stimulus displays are shown as examples. All numerosities were used as nonmatch stimuli (probability = 0.125) for the respective sample numerosities. The crow had to peck the test1 display if it contained the same number of items as the sample and had to refrain from pecking if it did not (probability = 0.5). After a 600-ms presample period, a sample stimulus was presented for 800 ms, followed by a 1,000-ms delay. The crow initiated a trial by keeping its head still in front of the monitor (automatically detected) to activate a go stimulus. Task protocol, stimuli, and behavioral performance. Here, we show that neurons in the telencephalic NCL of corvid songbirds respond to numerosity and show a specific code for numerical information. Where and how numerosity is encoded in vertebrates lacking a neocortex is unknown. Instead, birds developed different pallial parts as dominant endbrain structures ( 20, 21) based on convergent evolution, with the nidopallium caudolaterale (NCL) as a high-level association area ( 22– 26). The birds’ lineage diverged from mammals 300 Mya ( 19), at a time when the neocortex had not yet developed from the pallium of the endbrain. In contrast to primates, birds lack a six-layered neocortex. The neuronal correlates of numerosity representations have only been explored in humans ( 7– 9) and primates ( 10– 18), and they have been found to reside in the prefrontal and posterior parietal neocortices. As well as my friends and I will let as many parents know as possible.Birds show elaborate quantification skills ( 1– 3) that are of adaptive value in naturalistic situations like nest parasitism ( 4), food caching ( 5), or communication ( 6). If this school doesn't get it together I am out. I am not paying for my child to learn at an orphanage during the day. Back to the building-The jungle gym has nails poking out of it, the toys are absolute filth and look like they are all missing pieces and second handed. It took all of my might not to give a piece of my mind. Especially in the pre-k and older toddler class. Also, more than once I saw and heard teachers saying very vulgar things. I want my childrens teachers to be in the classroom not preoccupied with a mop or dishes. I asked about it and it turns out they make the teachers do it. I learned that they do not even have a janitorial staff or kitchen hand. But speculating and just walking around the school to check it out whil waiting for my kids to finish up I was ALARMED. I' m sorry but I want-no,I NEED to know who is around my child. Not even counting the random people they just throw in the classroom without sending parents an email. My son alone had 3 different teachers in ONE year. YOU KNOW something is awful with management when a school can't keep great teachers. But lets start with my top complaints cleanliness and teacher turnaround. The kids get to be socialized,indoor play area etc. First off I thought it sounded great,amazing really. I've had 2 kids here and my friends children went here for a very short time.
