         that a potential delisting would have on the Merger.
3.       Please revise your disclosure in this section, and elsewhere in the
prospectus, as
         appropriate, to briefly discuss whether the execution of the Reverse
Split would impact
         the percentage of stock owned in the combined company by Vallon   s
current stockholders
         following the Merger.
4.       Please revise your disclosure in this section to include a question
and answer, or multiple
         questions and answers, specifically addressing the following points:

                Disclose potential exchange ratios at (i) various levels of
Vallon   s net cash and (ii)
              potential required reductions to Vallon   s valuation required in
order to meet Nasdaq   s
              listing requirements. In your revisions, please show ownership in
the combined
              company among GRI   s equityholders, Vallon   s equityholders and
the Investor.
                Disclose whether you anticipate that Vallon   s valuation will
need to be reduced in
              order to meet the initial listing requirements of Nasdaq, based
upon currently
              available information and the current trading price of Vallon   s
common stock.
                Disclose potential exercise prices of the Series A-1, A-2 and T
Warrants based upon
              currently available information, including the potential for
cashless exercises.
                Disclose fully-diluted ownership in the combined company,
including the Series A-1,
              A-2 and T Warrants.

combined company.
Prospectus Summary
Opinion of Vallon's Financial Advisor, page 15

6.       Please revise your disclosure here and throughout the prospectus where
the fairness
         opinion is described to reflect your statement on page 103 that, at
the request of the Vallon
         Board, for the purposes of its opinion, Ladenburg assumed that no
"Adjustment" (as
         defined on page 103) would occur despite management of Vallon advising
Ladenburg
         that, as of the date of the opinion, such an Adjustment would be
required. Please also
         revise here and on page 103 to explain why the Vallon Board instructed
Ladenburg to
         prepare its opinion without incorporating an Adjustment, despite
Vallon's management
         advising that an Adjustment would be required.
7.       We note your statements here and elsewhere in the prospectus, as well
as in the fairness
         opinion attached as Annex G, that the opinion is intended for the sole
benefit of Vallon's
         board of directors. Please remove this statement.

         Alternatively, please disclose the legal basis for your and
Ladenburg's belief that
         stockholders cannot rely on the opinion to bring state law actions,
including a description
         of any state law authorities on such a defense. If no such authority
exists, please disclose
         that this issue will be resolved by a court, resolution of this issue
will have no effect of on

         rights and responsibilities of Vallon's board under state law and the
availability or non-
         availability of this defense has no effect on the rights and

Risk Factors
Litigation relating to the Merger could require Vallon or GRI to incur
significant costs..., page 30

8.       Please revise this risk factor to disclose if the parties are aware of

litigation, please include
         an affirmative statement to that effect.
The Merger
Background of the Merger, page 93

9.       Please revise your disclosure to state why Vallon's management chose
to re-engage in
         discussions with Company A in early September ahead of re-engaging in
discussions with
         GRI and describe the terms upon which Vallon and Company A were unable
to reach
         agreement.
10.      We note your statement that changes to GRI's proposal included a
revised budget that
         could achieve major milestones with less pending than originally
proposed and a
         willingness to revise relative valuation and ownership in the merged
company. Please
         quantify both the valuation in GRI's initial proposal and final
valuation attributed to GRI.
         To the extent there is a material difference in the initial and final
valuation, include
         disclosure explaining the reasoning for such changes. Please also
revise this section to
         include a more fulsome discussion of the negotiations of the Exchange
Ratio. Finally,
         please revise to describe the details of the revised budget and the
major milestones
         included therein.
11.      Please revise your disclosure in this section to describe the
discussions and negotiations
         with the Investor leading to the Equity Financing.
Vallon Reasons for the Merger, page 97

12.      Your disclosure here and on page 14 indicates that the Exchange Ratio
formula is based
         on a Vallon valuation of $26.0 million. However, disclosure elsewhere
in the prospectus,
         including on page 1, indicates that the Exchange Ratio formula is
based on a Vallon
         valuation of $29.0 million. Please reconcile your disclosure or
advise.
Opinion of Vallon's Financial Advisor, page 102

13.      We note your disclosure on page 103 that Ladenburg Thalmann & Co. Inc.

relied to render
         its fairness opinion.

15.      Please revise this section, where appropriate, to include a discussion
of the manufacture
         and supply of your product candidates. To the extent material, please
ensure that your
         discussion reflects your statement on page 78 that you are reliant on
a sole supplier, or, in
         some cases, a limited number of suppliers, for the manufacture of your
product
         candidates.
Overview, page 167

16.      We note your statement that you are initiating a Phase 1a/1b trial of
GRI-0803 and your
         disclosure here and on page 169 that you anticipate topline results
from this trial to be
         available in the second quarter of 2024. However, we note that you do
not appear to have
         an active IND for this trial. Please refrain from making predictions
that assume successful
         clearances of INDs or successful clinical trials. You may state when
you intend to submit
         your IND for this trial.
Our Pipeline, page 168

17.      Please revise your pipeline table to shorten bar for GRI-0803 as
disclosure on page 180
         indicates that you have not yet submitted an IND for this candidate,
or advise. Please also
         remove the blue arrows and text from the pipeline arrows. Finally,
based on your
         disclosure on pages 54 and 109, neither GRI-0124 nor GRI-0729 is
currently in
         development. Please remove these candidates from your pipeline table.
We do not object
         to narrative discussion of GRI-0124 and GRI-0729 in the GRI Business
section.
18.      Please revise here, or elsewhere in the Business section, as
appropriate, to discuss in
         further detail the results from your pilot Phase 2a trial of GRI-0621,
including whether the
         trial achieved its endpoints, the frequency and nature of any observed
adverse events and
         if adverse events were linked to treatment.
Description of Vallon Capital Stock
Choice of Forum, page 255

19.      Please include a risk factor discussing the risks to investors arising
from the Choice of
         Forum provision of Vallon's certificate of incorporation. Risks may
include, but are not
         limited to, increased costs to bring a claim and that these provisions
can discourage claims
         or limit investors' ability to bring a claim in a judicial forum that
they find
         favorable. Please also disclose whether this provision applies to
actions arising under the
         Securities Act. In that regard, we note that Section 22 of the
Securities Act creates
 David Baker

      concurrent jurisdiction for federal and state courts over all suits
brought to enforce any
      duty or liability created by the Securities Act or the rules and
regulations thereunder. If
      the provision applies to Securities Act claims, please also revise your
disclosure to state
      that there is uncertainty as to whether a court would enforce such
provision and that
      investors cannot waive compliance with the federal securities laws and
the rules and
      regulations thereunder. If this provision does not apply to actions
arising under the
      Securities Act, please also ensure that the Choice of Forum provision in
the certificate of
      incorporation states this clearly, or tell us how you will inform
investors in future filings
      that the provision does not apply to any actions arising under the
Securities Act.
