  • "If you want quality and wonderful service, please go to Dr. Shalu Pal! The patience, care, and true concern that Dr. Pal has for her clients is wonderful. "

    --Seleena J
  • " I was pleasantly surprised by finding a hidden gem within Dr. Pal's office"

  • "Finally a doctor who is extremely knowledgeable, patient and explains things clearly. She is a wonderful human being who really takes the time to care for your needs. The office has a wonderful atmosphere and the staff are just as helpful as Dr. Pal. "

  • "I couldn't ask for a better Optometrist. She is a delight to deal with, very patient, helpful and extremely knowledgeable. She was very good with my kids who can be very fussy at times.. And who could ask for a more beautiful location. Highly Recommend! "

    --Natalie M.
  • "My wife and I, highly recommend Dr. Pal. The staff, the service, the merchandise, are all top notch. They really make you feel welcomed. It has been several years since I have been able to see this well !!! You and your staff are the best !!!! "

    --Steve and Maria L.
  • "We barely go to optometrists so when we do, we should look for the best! I am super pleased I chose Dr. Pal\'s office. They were helpful from beginning to end, from booking on the phone to my actual visit. Dr. Pal was very detailed and went in-depth about my eye health. She is very patient and made me feel calm. The optician helped me pick a great pair of glasses, they were genuinely friendly which is a huge bonus."

  • "I have been going to Dr. Pal for several years now. My most recent visit on June 6, 2016 was the best experience there that I have ever had. Firstly, the women on the desk were friendly and efficient - a very good prelude to my examination. Dr. Pal, herself, was, as usual, very thorough and encouraging in her examination. And she puts you at ease before we get into the eyes examination by discussing other things in life. That helps to ease any stress I may have. And they now have a man in the office who does that difficult examination (name of which I do not know!). He is so patient and encouraging and made the exam not so difficult for me this time. After all that, I saw Dr. Pal again before I left and she told me my eyes were good! Even had the news been not so good, I believe that I would be able to handle it because I truly believe that Dr. Pal and her staff would have taken good care of me. I will always go back to Dr. Pal and members of her team because I truly believe"

  • " I have been to a few appointments at Dr. Pal\'s office over the last year for dry eye issues and every time it has been a very positive experience. The 3 receptionists at the front desk are warm and friendly. They are attentive and provide a very high level of customer service. I appreciate that they call me by name and remembered conversations we had at previous visits. I find Dr. Pal to be an excellent practitioner who is very thorough with her exams, has a lovely personality and takes the time to answer any and all questions that may arise. I am happy with the computer glasses I purchased and value the honest opinions I received from the staff when selecting frames. It was refreshing to have multiple opinions on styles and I felt they truly wanted me to walk out with a frame that was best suited to me. I highly recommend Dr. Pal \'s office! As a health care practitioner myself, I think all health care experiences should be this personilzed and friendly!"

The Human Brain Can Recognize Objects Much Faster

The Human Brain Can Recognize Objects Much Faster Than Previously Thought

Human beings far outpace computers in their ability to recognize faces and other objects handling with ease variations in size color orientation lighting conditions and other factors. But how our brains handle this visual processing isn t known in much detail. Researchers at Children s Hospital Boston taking advantage of brain mapping in patients about to undergo surgery for epilepsy demonstrate for the first time that the brain at a very early processing stage can recognize objects under a variety of conditions very rapidly. The findings were published in the journal Neuron on April 30th.

Visual information flows from the retina of the eye up through a hierarchy of visual areas in the brain finally reaching the temporal lobe. The temporal lobe which is ultimately responsible for our visual recognition capacity and our visual perceptions also signals back to earlier processing areas. This cross-talk solidifies visual perception.

"What hasn t been entirely clear is the relative contribution of these "feed-forward" and "feed-back" signals " says Gabriel Kreiman PhD of the Department of Ophthalmology at Children s Hospital Boston and the study s senior investigator. "Some people think that if you don t have feedback you don t have vision. But we ve shown that there is an initial wave of activity that gives a quick initial impression that s already very powerful."

Although feedback from higher brain areas may occur later and is often important very fast visual processing would have an evolutionary advantage in critical situations such as encountering a predator Kreiman adds.

Previous human studies have relied on noninvasive brain monitoring either with electrodes placed on the surface of the head or with imaging techniques and have captured brain activity at intervals of seconds - lagging considerably behind the brain s actual processing speeds. Moreover these techniques gather data from fairly general brain locations. By placing electrodes directly on the brain the Children s researchers were able to obtain data at extremely high temporal resolution - picking up signals as fast as 100 milliseconds (thousandths of seconds) after presentation of a visual stimulus - and monitor activity in very discrete specific locations.

Kreiman collaborated with Children s neurosurgeon Joseph Madsen MD who was already doing brain mapping in patients with epilepsy a procedure that ensures that surgery to remove damaged brain tissue will not harm essential brain functions. The team implanted electrodes in the brains of each of 11 adolescents and young adults with epilepsy (anywhere from 48 to 126 electrodes per patient) in the areas where their seizures were believed to originate.

While the electrodes recorded brain activity the patients were presented with a series of images from five different categories - animals chairs human faces fruits and vehicles - of different sizes and degrees of rotation. The recordings demonstrated that certain areas of the brain s visual cortex selectively recognize certain categories of objects responding so strongly and consistently that the researchers could use mathematical algorithms to determine what patients were viewing just by examining their pattern of neural responses. Moreover these responses occurred regardless of the object s scale or degree of rotation. And recognition was evident within as little as 100 milliseconds too fast for information to be relayed from the visual cortex to the temporal lobe and back again. Kreiman and Madsen are now extending these studies by showing patients movies - more closely resembling the way we see images in real life. Since each patient is allowed to choose his or her own movie Kreiman s team must analyze its visual content frame by frame and then link that data to the patient s brain activity.

Why is it important to tease apart visual processing in this way? Kreiman envisions using the vision algorithms discovered in humans to teaching computers how to see as well as people so that they could help in real-life applications such as spotting terrorists in airports helping drivers avoid collisions with hard-to-see pedestrians or analyzing hundreds of tumor samples looking for malignancy. A more futuristic application would be the design of brain-computer interfaces that would allow people with visual impairment to have at least partial visual perception.

Over the last decade Kreiman and Itzhak Fried MD PhD of UCLA have studied the hippocampus which is involved in memory and found individual brain cells that responded consistently when people were shown specific images such as pictures of Jennifer Aniston and Bill Clinton. Kreiman is interested in further exploring the relation between visual processing and memory and incorporating the physiological knowledge into computational algorithms. The current study was funded by the Epilepsy Foundation the Whitehall Foundation the Klingenstein Fund and the Children s Hospital Boston Ophthalmology Foundation.
