Our new paper on the encoding of amplitude modulation in NHPs is out now, see thread by lead author Chase Mackey below!
journals.physiology.org
Sinusoidal amplitude modulation (SAM) is a key feature of complex sounds. Although psychophysical studies have characterized SAM perception, and neurophysiological studies in anesthetized animals...
At long last, our (@RamRamLab) paper on the subcortical encoding of sound envelope is out! 🔊🐒. Thread below. Ahead of print paper at J Neurophysiol: . Preprint:

We are so proud of legendary Ram lab alumnus @Jane_Mondul !.
We're excited to welcome @Jane_Mondul as an Assistant Professor to @PurdueSLHS! Her expertise and commitment to her field will undoubtedly benefit both our students and the broader Purdue SLHS community. Please join us in welcoming her!. #PurdueSLHS #PurdueHHS #Audiology

Former Ram lab member doing his postdoc with Charlie Schroeder 👇🏼.
If you’re interested in multisensory integration 🦻👀, face/vocalization perception in monkeys🐒, or cortical microcircuits, take a look:. Our new paper on the laminar pattern of visual, and audiovisual, responses across the cortical hierarchy is out now.

Ram lab alumnus 👇🏼 we like him even though he studies the cortex now.
Our poster is up on the @SfNtweets website! I’ll be representing the Translational Neuroscience Division at Nathan Kline Institute in person on Monday. Come talk thalamocortical circuits and rhythm! Details below.

Detection of sounds is a fundamental function of the auditory system. Although studies of auditory cortex have gained substantial insight into detection performance using behaving animals, previous...
Our new preprint is up! We report correlations between single-unit activity and detection performance, and we report subcortical choice probabilities exceeding those typically reported in sensory cortex. (1/2).

Another successful dissertation from our lab! Chase will be working with Charlie Schroeder, @realnicenelly and @AnnieBarczak at Nathan Kline Institute in his next phase.
Proud of our friend and collaborator, @Chase_Mackey of @RamRamLab, for successfully defending his thesis yesterday. He will soon be moving up to NY to start a postdoc with Charlie Schroeder at the Nathan Kline Institute. Keep an eye on him, we know he is destined for big things!

It’s been a wonderfully productive Summer for our lab. We have one more for you. Check out our new preprint below.
🙈🔉 new preprint 🔉🙈. We used single neurons, populations, and computational modeling to find that subcortical spiking activity and a temporal integration model accounted for primate sound envelope discrimination. (1/3).

We hope these data will lay the groundwork for future studies investigating the effects of subclinical pathologies and contribute to the development of an improved audiologic test battery for differentially diagnosing auditory disorders.

Check out our new paper in Hearing Research, which, to our knowledge, is the first single reference with a comprehensive normative characterization of clinically traditional and clinically novel metrics and stimuli in DPOAEs and ABRs in a young cohort of 36 male macaque monkeys.

We are super excited to see what the future holds for Jane!.
On 5/9/22, I defended my dissertation! 👂🧠🐒 It was surreal to reach this culminating step in my graduate education, and to have so many colleagues, friends, and family in attendance. Next I’m headed to Johns Hopkins for my postdoc with the Glowatzki and @LauerLab! #audphd

Even in science, you can make lemonade out of lemons. Check out our newest publication by @Jane_Mondul, @Chase_Mackey, and our veterinary colleagues describing the effect of chronic otitis externa on auditory function. @AALASnational #comparativemedicine .
