<p>Hi Robert,</p>
<p>I was a friend of Charlies in princeton from the 80s. Charlie died in 2019. </p>
<p>And we had many dinners together.. occasionally with his most recent wife, Joyce Carol Oats.</p>
<p>Charlie argued his face cells (and hand cells0 were not grandmother cells: they were coarsely tuned, responded to many faces, and fit an ensemble/population code.</p>
<p>Its hard to fight a counterfactual, as there are too many ways a concept or category intension could be false. How many control conditions do you need before it is categorical response to a specific stimulus? Is an equivalence class enough for it to be
categorical? Same problem with so called fuisform face area.. </p>
<p>A relevant paper to this is something I wrote a few years ago in Frontiers, Human Neuroscience.. The </p>

BTW, I talked to Charlie Gross about all this in the 1980s or 90s - I haven’t talked to him about this more recently so his views might have changed. I also knew Horace Barlow a bit, but my conversations with him were about artificial neural nets and computation
(again in the 80s and 90s), not neurophysiology. At the first talk I ever gave I notice Horace in the audience and shuddered - he was a bit terrifying to a young neophyte. He did ask a question at the end of my talk, but it wasn’t one that stumped me, and
he was very gracious about the whole thing.</div>

<span style="font-size: 11pt;">Charlie Gross was in that discussion with Horace Barlow. So was Itzhak Fried and Christof Koch. The referenced Jennifer Aniston experiments were conducted under their guidance at UCLA. And so was Walter Freeman and many other
prominent neuro and cognitive scientists involved in that discussion.</span></p>
<p class="MsoNormal" style="margin: 0in 0px; font-family: Aptos, sans-serif; font-size: 12pt;">
<span style="font-size: 11pt;"> </span></p>
<p class="MsoNormal" style="margin: 0in 0px; font-family: Aptos, sans-serif; font-size: 12pt;">
<span style="font-size: 11pt;">Gross (2002) characterized grandmother cells as “multimodal.” Reddy and Thorpe (2014) also define concepts cells as “invariant, multimodal.” Thus, the fundamental characterization of these two concepts is identical. “Multimodal
invariance” implies associative learning across modalities. They also state that concept cells have “<b><i>meaning</i></b> of a given stimulus in a manner that is
<b><i>invariant</i></b> to different representations of that stimulus.” </span></p>
<p class="MsoNormal" style="margin: 0in 0px; font-family: Aptos, sans-serif; font-size: 12pt;">
<span style="font-size: 11pt;"> </span></p>
<p class="MsoNormal" style="margin: 0in 0px; font-family: Aptos, sans-serif; font-size: 12pt;">
<span style="font-size: 11pt;">“<b>Selectivity or specificity</b>,” “<b>complex concept</b>,” “<b>meaning</b>,” “<b>multimodal invariance</b>” and “<b>abstractness</b>” (Reddy and Thorpe, 2014) are all integral properties of both concept cells and grandmother
cells. </span></p>
<p class="MsoNormal" style="margin: 0in 0px; font-family: Aptos, sans-serif; font-size: 12pt;">
<span style="font-size: 11pt;"> </span></p>
<p class="MsoNormal" style="margin: 0in 0px; font-family: Aptos, sans-serif; font-size: 12pt;">
<span style="font-size: 11pt;">Reddy and Thorpe (2014) categorically state that “<b><i>abstract, invariant representations</i></b>” is “<i>a hallmark of MTL concept cells</i>.” Quiroga (2012) also admit that concept cells are abstract: “<i>These and many other
examples suggest that MTL neurons encode an </i><b><i>abstract</i></b> <b>representation</b> of the concept triggered by the stimulus.”</span></p>
<p class="MsoNormal" style="margin: 0in 0px; font-family: Aptos, sans-serif; font-size: 12pt;">
<span style="font-size: 11pt;"> </span></p>
<p class="MsoNormal" style="margin: 0in 0px; font-family: Aptos, sans-serif; font-size: 12pt;">
<span style="font-size: 11pt;">Unfortunately, Barwich (2019) is completely flawed in its arguments against grandmother cells as argued in Roy’s commentary on the article (Roy (2020)).</span></p>
<p class="MsoNormal" style="margin: 0in 0px; font-family: Aptos, sans-serif; font-size: 12pt;">
<span style="font-size: 11pt;"> </span></p>
<p class="MsoNormal" style="margin: 0in 0px; font-family: Aptos, sans-serif; font-size: 12pt;">
<span style="font-size: 11pt;">The neurophysiological evidence for purely abstract single cell representation in the brain points to symbolic representation in the brain.
</span><span style="font-size: 11pt; color: black; background-color: white;">Quiroga et al. (</span><span style="font-size: 11pt;">2008</span><span style="font-size: 11pt; color: black; background-color: white;">) estimate that
<b>40% of MTL cells are abstract</b>. Thus, there is extensive use of abstractions at the single cell level in the brain. This is the neurophysiological evidence for the neurosymbolic approach and what Gary Marcus has been arguing for all along. In a way, both
approaches win and need each other.</span></p>

<span style="color: black;">It is worth pointing out that in Jerry Lettvin’s original paper on the grandmother cell the concept was presented as a joke. Lettvin certainly believed in the notion that one might identify cells in the frog’s brain as ‘bug detectors’,
but he appeared to be sceptical about the idea that such cells might exist in the human brain representing complex concepts like ‘my grandmother’. There are a couple of great papers on the history of the grandmother cell:</span></p>

<span style="color: black;">People often assume that the Quiroga et al (2005 Nature, 435. 1102 - 1107) paper on the Jennifer Aniston cell was positive evidence for the existence of grandmother cells in the human brain. This is far from the truth. The Jennifer
Aniston cell does not only respond to Jennifer Aniston, but also to related concepts like ‘Lisa Kudow’ (another actress in ‘Friends’), so activity in that cell does not uniquely code ‘Jennifer Aniston’ and cannot be used to read out the presence of Jennifer
Aniston. Quiroga et al make this clear in the discussion of their findings.</span></p>

Yes, historically this was an important meeting --and indeed the term AI was coined by John McCarthy who with several others put together the 1955 meeting; McCarthy also invented LISP after this meeting. Part of the AI meeting at DM was political. McCarthy
deliberately chose "Artificial Intelligence" partly to distance the new effort from Wiener's cybernetics and the neural network tradition. Which was thematic in the MACY meetings.. which ended in 1953--2 years before the "AI" meeting. McCarthy wanted to stake
out a separate field with a symbolic/logical emphasis (in contrast to McCulloch and Pitts). So the naming wasn't just descriptive; it was a bit of a territorial move that arguably sidelined neural networks for decades until the connectionist revival in the
1980s (sorry Juergen). And the more recent revolution associated with DL and LLMs more specifically. In the 1970s, this fueled the long term debate in Cognitive Science on Symbols/Rules vs Vectors/NN. </p>

I was there and gave a talk, the only one on neural networks. I learned a lot from the other speakers.<br>
<br>
I just listened to the questions at the end of my talk. I pretty much predicted what was going to happen in AI and thought it would take 50 years. I was wrong, it took less than 20 years.<br>
<br>
One of the questions at the end was about intelligent aliens who appear and don't have human brains.<br>
This was a set piece in my recent book on ChatGPT and the Future of AI, where ChatGPT is the alien.<br>
<br>
I gave my version of that meeting in my first book on the Deep Learning Revolution. Every talk that reported progress did so because they had enough data to analyze, including Gene Charniak who was trying to parse sentences and Takeo Kanade working on computer
vision (These two talks are not included in the list). At the end Marvin Minsky accused them for just working on applications, not real AI.<br>

In case you did not see this: Some amazing lectures and (now historical) perspectives… the most interesting parts are when they tried and predicted the future of AI!</p>

In 2006, we held a 50th anniversary conference at Dartmouth to commemorate</p>
<p class="MsoNormal" style="margin: 0in; font-family: Aptos, sans-serif; font-size: 12pt;">
the historic 1956 meeting that coined the term "artificial intelligence." At that time,</p>
<p class="MsoNormal" style="margin: 0in; font-family: Aptos, sans-serif; font-size: 12pt;">
five of the surviving original participants attended. Today they are all gone.</p>

INobody foresaw what is happening in AI today and in fact,</p>
<p class="MsoNormal" style="margin: 0in; font-family: Aptos, sans-serif; font-size: 12pt;">
there were several digs against neural networks etc. </p>
